The figure shows a thin rod, of length L = 2.20 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 9.70 kg is attached to the other end. The rod is pulled aside to angle θ0 = 5.4° and released with initial velocity v→0 = 0. (a) What is the speed of the ball at the lowest point? (b) Does the speed increase, decrease, or remain the same if the mass is increased?

Question
The figure shows a thin rod, of length L = 2.20 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 9.70 kg is attached to the other end. The rod is pulled aside to angle θ0 = 5.4° and released with initial velocity v→0 = 0. (a) What is the speed of the ball at the lowest point? (b) Does the speed increase, decrease, or remain the same if
the mass is increased?
