Two balls of masses Ma=40g and Mb=60g are suspended as shown in the picture in your text. The lighter ball is pulled away to a 60 degree angle with the verticle and released. a) What is the velocity of the lighter ball before imapct? b) What is the veloctity of each ball after the elastic collision? c) What will be the maximum height of each ball after the elastic collision. Relevant equations Im not sure how to incorporate the angle into the equations i know. I have the equations MaVa=MaV'aCosThetaa' + MbV'bCosThetab' The attempt at a solution I have not attempted to solve this the prime in the equation is throwing me off. Also I could easily solve this problem without the angle so I do not know how to incorporate this into the equations I know.
