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 lighter ball before impact? What is the velocity of each ball after the elastic collision? What would be the greatest height of each ball after an elastic collision?

Q2. An astronaut travels to an alternate universe that contains infinite charged plane and no other charged objects. The astronaut observes that the electric field in this universe has a magnitude of 1.20 N/C everywhere and points directly away from the plane. Establish the charge density of the plane.
