In a ballistics test, a 25.0 g bullet traveling horizontally at 1300 m/s goes through a 20.0 cm -thick 250 kg stationary target and emerges with a speed of 900 m/s . The target is free to slide on a smooth horizontal surface.

A) How long si the bullet in the target?

B) What averag force does the bullet exert on the target?

C) What is the target's speed just after the bullet emerges?
