Question

1) A bullet that has a mass of 0.1 kg has a velocity of 420 m/s just before it hits the 1.5 target. If the bullet continues with a speed of 300 m/s, how fast will the target be going after collision?


2) An 8.5 kg cart traveling at 9.54 m/s (this movement defines the positive direction) has a head on elastic collision with a 36.8 kg cart (v = 0). If the final velocity of the first cart is 3.57 m/s, what was the final velocity of the second part
