Question

8.1. Consider a student playing pool. He hits a cue ball with mass m and velocity v directly at another stationary ball of identical mass. These balls impact head on. After the collision, the cue ball is stationary and the other ball has velocity v 8.1.1 What is the momentum of the cue ball before the collision? 8.1.2 What is the momentum of the stationary ball before the collision? 8.1.3 What is the total momentum of the system (both balls together) before the collision? 8.1.4 What is the momentum of the cue ball after the collision? 8.1.5 What is the momentum of the other ball after the collision? 8.1.6 What is the total momentum of the system (both balls together) after the collision? 8.1.7 How does the momentum of the system before the collision compare to the momentum of the system after the collision?

Explanation / Answer

1. mv

2. Zero

3. mv

4. Zero
