A bullet with mass m hits a wooden block with mass m resting on a smooth horizontal plane with velocity v0. The average resistance of the bullet in the wooden block is f, and the velocity of the bullet after penetrating the wooden block is V1. Find out (1) the velocity of the bullet penetrating the wooden block and (2) the displacement of the wooden block

Find out (1) the velocity of the bullet penetrating the wooden block and (2) the displacement of the wooden block

1 v=m(v0-v1)/M
2 the displacement when the bullet is fired is s = MV2 / 2F
