Q1. Two balls, of masses = 43kg and = 65kg, are suspended. The lighter ball is pulled away to a 66 angle with the vertical and released. Assume that the positive axis is directed to the right. 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 highest height of each ball after the elastic collision?

Q2. A uniform horizontal bar of length L = 3 m and weight 226 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 20o with the horizontal. A mass M, with a weight of 347 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 596 N. What is the greatest possible distance from the wall at which mass M can be placed before the wire breaks?
