You are bowling and have one pin left standing. You roll the 10kg bowling ball at a velocity of +1 m s into the 1kg pin, which is at rest. After the ball hits the pin, the pin and the ball both travel along a straight line. If the ï¬nal velocity of the ball after it hits the pin is +0.9 m s , what is the kinetic energy of the pin after it is struck by the ball?
