Two balls, of masses mA = 40 g and mB =60g, are suspended each on a string of 30 cm long side byside, The lighter ball is pulled away to a 60 degree angle with thevertical and released.
a) what is the velocity of the lighter ball before impact?
b)what is he velocity of each ball after the elastic collision? c)what will be the maximum height of each ball after the elastic collision?
