A pool player uses the cue ball to make a direct hit on the 8-ball. The mass of each ball is 0.17 kg. Before the collision the cue ball moves at 7 m/s and the 8-ball is at rest.

Write the equation to find the total momentum before the collision.

What is the total momentum of the system before the collision?

If the cue ball stops after the collision, how fast does the 8-ball travel? Explain.

What is the total momentum after the collision?
