A 3.00 kg block of wood is suspended at rest by a thin thread attached to a supporting beam. A bullet of mass 32.0 g is fired vertica1ly upwards with velocity 415 m/s into the wood directly above it. The block and the bullet inside it move upwards together.

1 Determine the speed of the upward moving block and bullet immediately after the collision.

.

2 Calculate the total kinetic energy of the block and bullet immediately after the collision.

3 Calculate the maximum height the block and bullet reach.
