Question

a small bullet of mass m= 6 g staright up collides which a massive block of wood. At the time of impact of the speed of the bullet is V_i = 8 m/s. The block has a mass m= 5 kg and is initially vest on the table as shown in the picture. In the collision the bullet gets embeded in the block. After the collision the block and bullet system rises up to a maximum height H. The collision process is extremly fast and only last 0.0150s.

a) Calculate the final velocity of the block and bullet system imediately after the collision

b) The average force the bullet exerted on the block during the collision.

c) The average force the bullet exerted on the bullet during the collision

d) Maximum height that the block and bullet will rise after the collision

e) mechanical energy of the block and bullet lost during the collision.
