In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 45 cm thick 350 kg stationary target and emerges with a speed of 1000 m/s. The target is free to slide on a smooth horizontal surface. (a) How long is the bullet in the target (assume constant acceleration)? s What average force does it exert on the target? N (magnitude only) (b) What is the target's speed just after the bullet emerges?
