Two flexible balls rolling along a frictionless horizontal surface collide with each other. The Larger of the balls weighs 50g and the smaller weighs 30g. Immediately after the balls first touch each other ( the beginning of the collision), the center of mass of the larger ball is accelerating at a rate of 5m s-2 to the right. What is the acceleration of the center of mass of the smaller ball?
