What is Which of the following factor determines extent of wound caused by a bullet? and explain in detail?
A bullet's ability to wound is directly related to its kinetic energy (E=mv2/2) at the moment of impact. Because kinetic energy increases in direct propoion to weight (mass) of the missile and the square of its velocity, a bullet travelling at twice the speed of a second bullet of equal weight and similar shape, possesses four times much energy or wounding power.
