A thin block of soft wood with a mass of 0.070 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 591 m/s at a block of wood and passe through it. The speed of the block is 18 m/s immediately after the bullet exits the block. (a) Determine the speed (in m/s) of the bullet as it exits the block. m/s (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. (c) Verify your answer to part (b) by calculating the initial and final kinetic energies of the system in joules. KE KE
