A thin block of soft wood with a mass of 0.072 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 581 m/s at a block of wood and passes completely through it. The speed of the block is 16 m/s immediately after the bullet exits the block. Determine the speed of the bullet as it exits the block. m/s
