Solve the all parts of given question:
Question: A bullet of 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 0.095 kg. The block rests on a frictionless surface, and is thin enough that the bullet passes completely through it. Immediately after the bullet exists the block, the speed of the block is 23 m/s.
Part A: What is the speed of the bullet when it exits the block?
Part B: Is the final kinetic energy of this system equal to, less than, or greater than the initial kinetic energy? Explain.
Part C: Verify your answer to part (b) by calculating the initial and final kinetic energies of the system.
I need help to determine the speed of the bullet when it exits the block.
