Two balls, of masses = 43kg and = 65kg , are suspended as shown in the figure. The lighter ball is pulled away to a 66 angle with the vertical and released. Assume that the positive axis is directed to the right. What is the velocity of the lighter ball before impact? What is the velocity of each ball after the elastic collision? What will be the maximum height of each ball after the elastic collision?
