Instead of standing in the back of the lane and rolling the ball toward the pins like most people, you place a 5kg bowling ball at rest at the back of the lane and try to hit it toward the pins with a perfectly elastic collision using a 1kg ball rolling at 5 m/s from a 25 degree angle from the horizontal. Your perfect spin sends the larger ball flying or at least moving straight down the center of the lane toward the pin. What will the velocity of the larger bowling ball be?
