A thin block of soft wood with a mass of 0.080 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 609 m/s at a block of wood and passes completely through it. The speed of the block is 22 m/s immediately after the bullet exits the block. (NEED HELP WITH PARTS A + C )   (a) Determine the speed (in m/s) of the bullet as it exits the block   (b) Determine if the final kinetic energy of this system (block and bullet) is equal to, less than, or greater than the initial kinetic energy. (ALREADY SOLVED - LESS THAN)   (c) Verify your answer to part (b) by calculating the initial and final kinetic energies of the system in joules.   KEi= J KEf= J
