Question

The figure shows a thin rod, of length L = 1.00 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 7.90 kg is attached to the other end. The rod is pulled aside to angle ?0 = 17

The figure shows a thin rod, of length L = 1.00 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 7.90 kg is attached to the other end. The rod is pulled aside to angle ?0 = 17A degree and released with initial velocity = 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?

Explanation / Answer

the speed of the ball at the lowest point is 6876
