3. A billiard cue ball with a mass of 0.60 kg and an eight ball with a mass of 0.55 kg are rolled 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. The schematic diagram above shows the momentum vectors before and after the collision. m = 0.60 kg before after V = 3.0 m/s P c p' 8 Pc m = 0.55 kg V = 2.0 m/s P8 a. Determine the velocity of the eight ball
