In a ballistics test, a 25 g bullet traveling horizontally at 1200m/s goes through a 30 cm thick 350 kgstationary target and emerges with a speed of 900 m/s. The target is free to slide on a smoothhorizontal surface.
How long is the bullet in the target?
1s
What average force does it exert on the target?
N (magnitudeonly)
What is the target's speed just after the bullet emerges?
m/s
