The figure below shows a ball with mass m = 0.330 kg attached to the end of a thin rod with length L = 0.495 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed there. S L How much work is done on the ball by the gravitational force from the initial point to the following points? (a) the lowest point 1.60 J (b) the highest point -1.60 J (c) the point on the right level with the initial point 0 J If the gravitational potential energy of the ball-Earth system is taken to be zero at the initial point, what is it when the ball reaches the following points? (d) the lowest point X J (e) the highest point X J (f) the point on the right level with the initial point 0 J (g) Suppose the rod were pushed harder so that the ball passed through the highest point with a nonzero speed. Would AL from the lowest point to the highest point then be greater than less than or the same as it was when
