A bullet with a mass of 4.0 g and a speed of 650 m/s is fired at a block of wood with a mass of 9.7×10?2 kg. The block rests on a frictionless surface, and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 21 m/s.

A. What is the speed of the bullet when it exits the block?

B. Is the final kinetic energy of this system equal to, less than, or greater than the initial kinetic energy? & explain

C. Verify your answer to part B by calculating the initial kinetic energy

D. calculate final kinetic energy of the system.
