Location. MN. Mar 23, 2024. #33. Hit that North Dakota Buck with a nearly 2,288,000 grain slug ( 1997 GMC K-2500 Suburban ), that was traveling around 110FPS (75mph). A guy would think 61,468 ft lbs of energy would a stopped him, nope, not even a decent blood trail.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!In the world of physics there are various formulas for calculating the kinetic energy of different types of objects. Of course we are concerned with archery so we …Work is done on the object leaving it with 25 J of kinetic energy and 30 J of potential energy. How much work is done on the object? An object starts at rest from a height of 50 meters. Its total amount of mechanical energy is 500 Joules. The object begins a free-falling motion; there is no air resistance. When it has fallen to a height of 30 ...Meet the Energy Superbugs: Extremophiles. Keep reading to learn more about the energy superbugs, extremophiles. Advertisement Extremophiles are tiny microbes that are able to thriv...Science. Physics. Physics questions and answers. A proton is accelerated through a potential difference of 5.3 × 106 . a) How much kinetic energy has the proton acquired if its mass is 1.673 × 10−27 kg and the elemental charge is 1.602 × 10−19 C? Answer in units of J. b) If the proton started at rest, how fast is it moving? Answer in ...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 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 ...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.How much kinetic energy was lost in the collision? A 2100 kg car traveling at 12.0 m per s collides with a 2780 kg car that is initially at rest at the stoplight. The cars stick together and move 3.90 m before friction causes them to stop.For deer hunting, it is recommended to have a ballistic energy of at least 1,000 foot-pounds to ensure a clean and ethical kill. 1. What is ballistic energy? Ballistic energy is the measure of a bullet’s ability to penetrate its target. 2.The minimum fps (feet per second) needed to kill a deer with a crossbow is between 250-400 fps. This range provides the necessary kinetic energy to penetrate the hide and reach vital organs of the animal, resulting in an ethical and humane kill. It is important to note that higher speeds can cause too much tissue damage, which should be avoided ...But it all hinged on the kinetic energy transfer theory, which turns out to be incorrect. Where it All Goes Wrong. From at least the late 1800s through the Vietnam War, everyone assumed the kinetic energy transfer model was correct. The "shock" of getting hit by a fast-moving projectile and absorbing its kinetic energy contributed to ...Fort Shaw, Montana. Aug 26, 2010. #4. Foot Pounds of energy is a VERY poor way to determine if a cartridge will be effective at harvesting a deer or not. Let me explain, I have taken literally dozens of whitetail deer out to 300 yards using a 22-250 loaded with Hornady 55 gr SP bullets loaded to 3600 fps.Kinetic Energy is important for all bow hunters as it is the amount of killing power or hitting power our arrows hit the target with. Different areas have guidelines about the minimum kinetic energy needed to take big game animals. As a general rule of thumb for medium sized game such as deer, goat, antelope, and sheep, 40 ft-lbs. of Kinetic ...Nov 1, 2019 · Nov 7, 2019. #9. Those "rules" are from a long time ago. What you need is enough speed to cause the bullet to expand properly and enough energy to push that bullet through to the vitals. You definitely don't need 1200 or deer. 9mm kills deer just fine with 350 ftlbs of energy. Step 1. Course Home Homework 10 Problem 9.31 9 of 13 Review An air-track cart with mass m1 0.25 kg and initial speed vo 0.75 m/s collides with and sticks to a second cart that is at rest initially. PartA If the mass of the second cart is m2 0.49 kg, how much kinetic energy is lost as a result of the collision?Kinetic energy powers the bullet expansion and penetration that destroys tissue, and it is the destruction of tissue (vital organs if the shot is a good one) that kills the animal. All of the common revolver hunting cartridges (.357 Mag., .41 Mag., and .44 Mag.) are medium bore or big bore calibers. It is no secret that such calibers, primarily ... 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! Unlike larger calibers that aim for vital organs, .22LR requires targeting the brain stem for adult deer due to limited kinetic energy. Even then, there's no guarantee that it will kill a deer because the skull can deflect the round. There's simply insufficient bullet weight, muzzle energy, or knock-down power to kill a deer.Posts. 1,123. There is no regulation on FPS, only on page 24 of the regulations... " crossbows must have a draw length of at least 300 mm (11.8 in.) and a draw weight of at least 45 kilograms (99.2 lb.). At a minimum bolts must have a 22 mm (0.87 in) wide head with at least two sharp cutting edges." Find a bow that fits you, shoulder the bow ...

The 223 Remington is an amazing cartridge that can accommodate bullets ranging from 35 grains all the way up to 77 grain bullets. In general, most big game hunting cartridges will have heavier bullets as these will pack on more kinetic energy and penetrate deeper. Typically, these bullets weigh 60 grains or higher.In general, a good arrow speed for deer hunting is between 250 and 300 feet per second pending your TAW. This range of velocity with the correct arrow provides more than enough kinetic energy and momentum to effectively take down a deer while also maintaining accuracy at typical hunting distances.3,567. Location. Falls Church, VA. Sep 12, 2010. #3. Although I agree with bigngreen that 1000lbs of energy and a well placed shot will take elk, the conventional wisdom says you need 1500 pounds of energy. So I ran your load in exbal and found that you have 1500lbs of energy at 500 yards and 1000lbs at 800.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 …At reasonable straight-wall cartridge hunting distances, for both velocity and trajectory, there is no real out-and-out winner between .450 Bushmaster vs .350 Legend. Both shed velocity like mad, the Legend losing 29-percent of its muzzle velocity at the 200-yard mark and the Bushmaster 31 percent—1,648 fps and 1,515 fps respectively.

Because projectiles launched with compressed air generate substantially less terminal kinetic energy than projectiles launched with gunpowder. ... any airgun – is all about precise shot placement. Thus, the limits of the practical range for killing big game like deer and hogs humanely with the most powerful big-bore airguns, is 60-80 yards ...Jun 5, 2014 · Just the same, a 150-grain bullet at 2,700 fps from a .30-06 is markedly easier to connect at longer range than the .30-30 WCF at 2,200 fps. While velocity is part of the picture, it isn’t everything. Just the same, this all-around hunting rifle has plenty of velocity and penetration. Energy is just a paper number. Therefore, the heavier the missile, the more kinetic energy there is. Overall, it takes around 21 to 45 Joules of kinetic energy at the point of impact to pass through any large-sized animal. Body movement after a shot. There are certain telltale signs that show the hunter where the animal was hit based on the movement of the animal right after ...…
