Two balls, of masses m(a) = 40 g and m(b) = 60 g, aresuspended. The lighter ball is pulled away to a 60 degreeangle with the vertical and released.
(a) what is the velocity ofthe lighter ball before impact?
(b) What is the velocity of eachball after the elastic collisoin?
(c) What will be the maxiumumheight of each ball after the elastic collision?
