Obtain the speed of the bullet when it exits the block

Reference no: EM13676202

A bullet with a mass of 4.1 gram and a speed of 650 m/s is fired at a block of wood with a mass of 9.6 x 10 kilogram. 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 22m/s.

Part A Obtain the speed of the bullet when it exits the block?

Part B Find is the final kinetic energy of this system equal to, less than, or greater than the initial kinetic energy?
