Momentum and Impulse Assignment Booklet 2 3. A billiard cure ball with a mass of 0.60kg and a eight ball with a mass of 0.55 kg are rolled towards each other. The cue ball has a velocity of 3.0m/s E, and the eight ball has a velocity of 2.0m/s N. After the collision, the cue ball moves off at a velocity of 2.0 m/s, 40.0 N of E. a. What is the velocity of the eight ball after the collision? (6 marks) * Hint* it is very helpful to draw a diagram to represent the motion of the billiard balls before and after the collision
