Two balls, of masses mA = 45 g and mB = 65 g, are

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?
