A 5.0 m massless rod is held in place at a pivot point. The rod has a small mass of 2.5 kgs attached to it. It is pulled up by an angle of 25 degrees from the horizon and then released.

Required:
a. Rank the magnitude of the gravitational potential energy of the ball from greatest to lowest and explain your reasoning.
b. If friction is negligible what is the tension on the rod when + D the mass is at its lowest point?
