Asked by Jennifer
In the game of billiards, all the balls have approximately the same mass, about 0.20 kg. The cue ball moving west with a speed of 4.5m/s strikes another ball at rest. After the collision the cue ball moves at an angle of 55degree north of west and the other ball at an angle of 25 south of west. What is the speed of the cue ball and the other ball after the collision?
