Physics questions and answers. An air-track cart with mass m1=0.26kg and initial speed v0=0.90m/s collides with and sticks to a second cart that is at rest initially. If the mass of the second cart is m2=0.52kg, how much kinetic energy is lost as a result of the collision?The minimum kinetic energy required to humanely kill a deer is generally accepted to be around 1,000 ft. lbs., as stated in the “Harvesting Energy” report published by the Black Powder Cartridge News in 1997. However, this is just a minimum guideline and other factors, such as the size and vital organ location of the deer, can affect the ...At the end of the day, the question of draw weight doesn't matter as much as it once did to bowhunters — but 40 pounds is still a good starting point. Lighter than that will work, too, so long as you know the constraints and make the proper adjustments to your equipment. Get your camo fix at the Realtree store.A recent example that demonstrates this clearly is this video by DIY Sportsman. The data given spans arrow masses from 379.4 grains to 1163.5 grains. That is an increase in arrow mass of 207%—a tripling of arrow mass. The kinetic energy of the arrow leaving the bow increased from 73.3-77.9 ft·lb., a mere 6% increase.Nov 09, 2005 #6. I had a know it all at an archery shop (the shop keeper) tell me that my 50lb hickory bow that I shot through his chrony at 155 fps could not kill a deer because "you need at least 40 foot pounds of kinetic energy to kill a deer". Damon. flushls. 151.

The Deer Hunting is Located in 1017 Cambridge Court, Paris, AR, Arkansas, 72855. Telephone +479-963-8187, [email protected] As long as you make a good shot, that is. According to Easton, a 400 grain arrow traveling at the glacial speed of 170 feet-per-second has sufficient energy to harvest a mature deer. Heck, many kids bows can easily shoot such a light arrow faster than 170 fps, and I’ve seen such rigs do pass-throughs on deer! By Bob Robb. When discussing the penetrating ability of a hunting arrow, the two most commonly referred to factors are kinetic energy and momentum. The term kinetic …

A sledder has 700 J of potential energy and 100 J of kinetic energy at one point on a steep hill. How much kinetic energy will the sledder have at the bottom of the hill?

About Quizlet; How Quizlet works; Careers; Advertise with us; Get the app;Apr 20, 2021 · The unofficial rule regarding minimum KE to push an arrow through a deer is about 40 foot-pounds. Lower-poundage bows are slower than higher-poundage models. So, let’s say the bow is pushing a 350-grain arrow at 265 feet per second. That setup is delivering roughly 54 foot-pounds of KE and .411 slugs of momentum.

Energy gives us an idea of how much power there is to initiate things like bullet expansion and penetration, but does not guarantee that they will occur. It is generally recommended that a small bore (.24-.32 caliber) rifle bullet suitable for medium size (CXP2 class) game be carrying about 800 ft. lbs. of kinetic energy when it hits.It is generally accepted that it takes between 25-40 pounds of kinetic energy to kill a deer, and calculating kinetic energy is pretty easy: arrow speed x arrow speed x arrow weight / 450,240 = kinetic energy. For this example I chose the all-new Bloodsport Evidence model with a 400 spine to complete the calculation. These arrows weigh 9.1 ...10664 posts · Joined 2004. #6 · May 31, 2006. The typical posted minimum is 55 ft pounds, but I have personally killed quite a few with less before I knew any better. The deer didn't seem to notice. You need to find out your arrow speed and then calculate K.E. The formula is: speed x speed x arrow weight / 450240.I am building a pair of high performance long range muzzleloaders. My goal is 500 yards with enough energy to kill big bull elk while shooting BH209. Each of these guns have .45 caliber barrels. One is .451" and the other is .458". My hunting ML so far has been a .50 cal Omega with a 300 gr SST with 120 gr by volume 85 gr by weight of BH209.

How fast is fast enough? I like my crossbows to shoot a hunting-weight arrow with an initial velocity of at least 300 feet per second (fps.) That will both give your arrow enough kinetic energy (K.E.) to cleanly take any big-game animal, and reduce arrow trajectory at longer ranges, which makes accurate shooting easier.

Jul 5, 2021 ... Comments9 · Arrow Flight with Broadheads - The Science of Bowhunting · The Truth about Kinetic Energy and Momentum for Deer Hunting · What Matt...johnhames. Recurves effectively kill deer with 35 to 45 ft.lbs of KE. But that is getting close to the bounce off level of energy. One of the first deer I ever shot at was with a 50# recurve, 600 grain arrows and a cut on contact broad head at 10 yds. I unluckily hit a rib, I assume crosswise.The forces and kinetic energy required to penetrate the isolated heads of calves, adult beef cattle, sheep and red deer with a metal probe the same diameter as the bore of an experimental pistol were determined. Approximately 16 and 127 Joules were required to penetrate the heads of adult sheep and cattle, respectively.By Nahid May 17, 2023. Shooting a deer with a crossbow requires patience, skill, and knowledge of the animal. First, you must decide what type of arrow or bolt to use for your hunt. Heavier arrows are often preferred because they penetrate further into the target than lighter ones. Next, you must select an appropriate distance from which to shoot.Regenerative braking is a highly efficient process. Check out HowStuffWorks for information about how regenerative braking works. Advertisement ­ Every time you step on your car's ...There are several factors that go into the arrow speed equation. When shooting a compound bow, all things being equal, they are: Draw weight: The more draw weight you pull, the faster the arrow will fly. The rule of thumb is that for every 10 lbs. of draw weight your bow is reduced, raw arrow speed is reduced 15-20 fps.For a small deer like a fawn you will need around 30 foot-pounds of energy to kill it. For a medium-sized deer like a doe you will need around 40-50 foot-pounds of energy. For a large deer like a buck you will need 60+ foot-pounds of energy. As for where you should aim it depends on what kind of weapon you are using.

Dec 1, 2012 · To score an instant kill with the usual deer rifle, exact bullet placement is required in a vulnerable area. The required degree of bullet placement will vary almost directly in proportion to the size and life tenacity of the animal, but will be somewhat inversely proportional to the striking energy and momentum of the bullet provided that expansion and penetration are uniformly balanced. KE. ME is KE at the Muzzle. Hence the whole "Muzzle Energy" name versus "Kinetic Energy." Posted: 12/8/2014 12:07:34 PM EDT [#10] Aside from the energy, remember that the .224" bullet is substantially longer, which will cut a wider path. ... 22 Win Mag will easily kill deer and hogs Inside 100 yards witha good broadside shot if that is what you ...A Mosin effectively can kill a deer at 600 yards. It's a decent hunting rifle. The Mosin Nagant can be a great option for a hunting rifle. It fires s a powerful and highly functional 30 caliber bullet that rivals the 30-06. In fact, in many cases, it overpowers the 30-06. And it does this with lower chamber pressure.In terms of power, the airgun should generate minimum kinetic energy of 10 foot-pounds to be considered a legitimate hunting weapon. This minimum requirement is adequate for taking animals like rodents, most birds, and small game like squirrels and cottontail rabbits. Larger game requires more energy.It takes only a little algebra to show that Equation ( 4.1.4 4.1.4) follows from the joint conditions of conservation of momentum and conservation of kinetic energy. The first one ( pi p i = pf p f ) clearly has the form. m1v1i +m2v2i = m1v1f +m2v2f (4.1.5) (4.1.5) m 1 v 1 i + m 2 v 2 i = m 1 v 1 f + m 2 v 2 f.The 338 Win mag is a good cartridge for shorter ranges and has killed many deer, elk and Bear. ... Energy, or more properly kinetic energy, is 1/2 mass times velocity squared. Momentum is mass times velocity. As you can see velocity is much less important in momentum and the importance of mass, or weight, is much greater. ...

It takes only a little algebra to show that Equation ( 4.1.4 4.1.4) follows from the joint conditions of conservation of momentum and conservation of kinetic energy.

(To determine how much initial kinetic energy your own bow-and-arrow set-up has at the shot, the formula is which is arrow weight (mass) x velocity squared, divided by 450,240. Most experienced bear hunters I know believe that for averaged-sized bears taken at reasonable ranges — under ...What this data translates to is that while .410 slugs may provide sufficient energy within 50 yards, beyond that its efficacy begins to drop dramatically. In fact, according to some ballistician's recommendation of a minimum 1,000 foot-pounds of energy to ethically kill a deer, the .410 is inadequate even at the muzzle.An arrow or bolt’s kinetic energy is greatest immediately after being discharged from a crossbow’s string. This energy also dissipates rather quickly with each yard of arrow flight, meaning that a bolt or arrow strikes a target with much more kinetic energy at 20 yards than it does at 50 yards.

They penetrate well and stay together. I do ascribe to the 1500 ft-lbs delivered energy for Elk but the 2500 ft-lbs is perhaps now disproven for moose. In my opinion, deliverd energy should at least be 1500 ft-lbs or greater, ideally in the 2000 ft-lb range. After the shot, immediately reload and prepare to shoot again.

A 1 ms smack requires more acceleration to kill you than a 100 ms smack. Penetrating injuries to the head have a good chance of killing you. The army long used 58 ft-lbs as the energy of a projectile (bullet or fragment) needed to cause a casualty, but that just assumed a hit and not necessarily a hit to the head.Feb 19, 2024 · An FPS of 300-350 is considered ideal for deer hunting with a crossbow. 2. Can I use a crossbow with a lower FPS for deer hunting? While it is possible to use a crossbow with a lower FPS for deer hunting, it is not recommended as it may not provide enough speed and power for a clean and ethical kill. 3.

For all practical purposes, arrow mass does not affect arrow kinetic energy when the two arrows are fired from the same bow.At least when these arrows hit the deer they have a decent and more lethal amount of momentum. Let’s review my advice: 6 grains of arrow weight per pound of draw weight for bows in the 70-lb. range. 8 grains of arrow weight per pound of draw weight for bows in the 60-lb. range. 10 grains of arrow weight per pound of draw weight for bows in ... It’s only from 300 FPS and up that you get enough kinetic energy at all feasible hunting distances (up to 50 yards) to be able to comfortably hunt elk. As such we recommend that elk hunters stick to 300 FPS or more. For whitetail deer this requirement is lower – any crossbow 250 FPS and up will be a safe pick. The forces and kinetic energy required to penetrate the isolated heads of calves, adult beef cattle, sheep and red deer with a metal probe the same diameter as the bore of an experimental pistol were determined.

In addition to being a Level 2 U.S. archery coach, Mark Beck is a hunter and an engineer with Plano Synergy who has experience in designing both arrows and crossbows. He makes no secret which side of the argument he's on. "I want more kinetic energy to drive that broadhead through," he said. o'reilly auto parts hobart indiana The highest velocity came from the "BMK 19"-0.18 inch (4.5 mm) air rifle with a velocity of 886 ft/s (270 m/s) and carrying an initial kinetic energy of 12.19 ft-lb (16.58 J). Depending on pellet type used, this led to penetration of a pellet into ballistics gelatin between 1.97 inches and 3.7 inches (50 mm and 94 mm) when fired from 65.6 ... camp creek soul festival In general, an arrow loses five feet of its kinetic energy per 10 yards after impact. So for a 40 lb bow firing out a 300 grain arrow at 230 fps for 50 yards shot from this same bow will only have 28 feet-lbs left upon impact at impact. As such, less kinetic energy is required than many hunters believe to kill a deer. First, we need to convert km/h to m/s, which gives us 27 / 3.6 = 7.5 m/s. Then we apply the first equation since we know the deformation distance, which is 75 cm = 0.75 meters. Replacing in the formula we get F avg = 0.5 · 2400 · 7.5 2 / 0.75 = 90 kN and a maximum impact force of 180 kN. ( calculation link) jinx manhwa read free Mar 18, 2014 ...
