A steel ball with mass m is suspended from the ceiling at the bottom end of a light, 29.0-m-long rope. The ball swings back and forth like a pendulum. When the ball is at its lowest point and the rope is vertical, the tension in the rope is three times the weight of the ball, so T=3mg.
Required:
a. What is the speed of the ball as it swings through this point? Express your answer with the appropriate units.
b. What is the speed of the ball if T=mg at this point, where the rope is vertical? Express your answer with the appropriate units.
