Q. A bowling ball with a mass of 6.8 kg strikes a stationary pin that has a mass of 1.6 kg. After the collision, the pin flies forward (in the positive x direction) with a velocity of 7.3 m/s, and the ball continues forward at 3.2 m/s (in the positive x direction). What was the original velocity of the ball? How do you solve this?
