# Question

A new crowd control method utilizes “rubber” bullets instead of real ones. Suppose that, in a test, one of these “bullets” with a mass of 500 g is traveling at to the right. It hits a stationary target head-on. The target’s mass is 25.0 kg and it rests on a smooth surface. The bullet bounces backward (to the left) off the target at 100 m/s.

(a) Which way must the target move after the collision: (1) right, (2) left, (3) it could be stationary, or (4) you can’t tell from the data given?

(b) Determine the recoil speed of the target after the collision.

A 0.150-kg baseball traveling with a horizontal speed of 4.50 m/s is hit by a bat and then moves with a speed of 34.7 m/s in the opposite direction. What is the change in the ball’s momentum? A small asteroid (mass of 10 g) strikes a glancing blow at a satellite in empty space. The satellite was initially at rest and the asteroid was traveling at 2000 m/s. The satellite’s mass is 100 kg. The asteroid is ...At a county fair, two children ram each other head-on while riding on the bumper cars. Jill and her car, traveling left at 3.50 m/s, have a total mass of 325 kg. Jack and his car, traveling to the right at 2.00 m/s, have a ...A fellow student states that the total momentum of a three-particle system (m1 = 0.25 kg, m2 = 0.20kg, and m3 = 0.33kg) is initially zero.
