<prompt> Which of the following factor determines the destructive power of bullet after firing?Weight of bulletShape of bulletSize of bulletVelocity of bullet  <response>: A bullets ability to injure is directly related to its kinetic energy at the moment of impact. Kinetic energy i.e. E mv2 2 The kinetic energy is directly propoional to weight mass of the bullet and the square of its velocity. Thus a bullet traveling at twice the speed of a second bullet of equal weight and similar size and shape, possesses four times much energy and injuring power.
