Two balls, of masses mA = 32 g and mB = 72 g are suspended as shown in Figure 7-44. The lighter ball is pulled away to a 60° angle with the vertical and released.

Figure 7-44
(a) What is the velocity of the lighter ball before impact? (Take the right to be positive.)
m/s
(b) What is the velocity of each ball after the elastic collision?
ball A m/s
ball B m/s
(c) What will be the maximum height of each ball (above the collision point) after the elastic collision?
ball A m
ball B m
