Two balls, of masses mA = 40 g and mB = 64 g are suspended. The lighter ball is pulled away to a 60 degree angle ( in the negative x direction) with the vertical and released. The height from which mA and mB are hanging is 30 cm.
a) What is the velocity of the lighter ball before impact? (Take the right to be positive.)
b) What is the velocity of each ball after the elastic collision?
c) What will be the max height of each ball (above the collision point) after the elastic collision?
