Two figure skaters, one weighing 625 N and the other 725 N, push off against each other on frictionless ice. (a) If the heavier skater travels at 1.50 m/s, how fast will the lighter one travel? (b) How much kinetic energy is "created" during the skaters' maneuver, and where does this energy come from? 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! ….

A company spokesman said: An old rule of thumb is that it takes 1,000 ft-lbs of energy to kill a deer. The 20 gauge has plenty of energy. For example, the Winchester Supreme 2¾” 20-gauge Partition Gold load uses a 260-grain bullet with a muzzle velocity of 1,900 fps and a muzzle energy of 2084 ft lbs.Let's say you're shooting a heavier arrow that weighs 500 gr. That means it has about 64 ft-lbs of kinetic energy when it leaves the bow. During the flight, some of that energy will be lost to wind resistance. When the arrow makes the impact with the deer, all of the remaining energy is transferred to the razor sharp edges of the broadhead.The relativistic kinetic energy is given by KE = m 0 c 2 (√(1 − v 2 /c 2) − 1), where m 0 is rest mass, v is velocity, and c is the speed of light. This formula takes into account both the total rest mass energy and kinetic energy of motion.Due to lower energy level a slight imperfection in shot placement can result in a lost animal. ...
