Physics 30 - Assignment 2 3. A billiard cue ball with a mass of 0.60 kg and an eight ball with a mass of 0.55 kg roll toward each other. The cue ball has a velocity of 3.0 m/s at 0 and the eight ball has a velocity of 2.0 m/s at 90. After the collision, the cue ball moves off at a velocity of 2.0 m/s at 40. Include vector diagrams in your answer to show how you determined the missing values for both the eight ball and the cur ball. m = 0.60 kg before after v = 3.0 m/s Pc Pa m =0.55 kg v = 2.0 m/s Pa a) Determine the velocity of the eight ball. /6 10
