In a ballistics test, a 25g bullet traveling horizontally at 1200m/s goes through a 30-cm-thick 350kg stationary target and emerges with a speed of 900m/s. The target is free to slide on a smooth horizontal surface. What is the target's speed just after the bullet emerges? Prove that this collision is inelastic, describe what happens to this lost kinetic energy.
