Chapter 7, Problem 78GP(choose chapter or problem)
Two balls, of masses \(m_A=45\mathrm{\ g}\) and \(m_B=65\mathrm{\ g}\), are suspended as shown in Fig. 7-46. The lighter ball is pulled away to a \(66^{\circ}\) angle with the vertical and released. ( ) What is the velocity of the lighter ball before impact? ( ) What is the velocity of each ball after the elastic collision? ( ) What will be the maximum height of each ball after the elastic collision?
