It penetrates inside the target through distance d = 3.75 cm and then stops. mass of the bullet is m = 1 kg and of the target is M = 4 kg. Now an identical bullet moving with the same velocity is fired on the identical target which is placed at rest on a frictionless horizontal surface. Then find the distance (in cm) to which the bullet will penetrate inside the target?

A particle of mass m makes an elastic head on collision with a stationery particle of mass 2m. If initial kinetic energy is moving particle is 6 j then during the impact
