Two balls of masses m1 = 50 g and m2 = 70 g are suspended as shown below. The length of the string is 55 cm. The lighter ball is pulled away at 45 degrees angle with the vertical and released. (a) What is the velocity of the lighter ball before the impact? (b) What are the velocity of each ball after the elastic collision? (c) What is the maximum height of each ball after the elastic collision? (d) What are the coordinates of
the CM of the two balls when the lighter ball was pulled up? Consider the heavier ball to be at the origin before the collision.
