In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 30-cm-thick 400 kg stationary target and emerges with a speed of 930 m/s. The target is free to slide on a smooth horizontal surface.
(a) How long is the bullet in the target?
What average force does it exert on the target?
(b) What is the target's speed just after the bullet emerges?
