A ball of mass m = 0.320 kg is connected by a light but rigid rod of length L = 0.770 m to a pivot and held in place with the rod being vertical. A wind exerts a constant force F to the right on the ball. The ball is released from rest, and the wind makes it swing up to a maximum height Hmax above its starting point before it swings down again.
(a) Find Hmax when F = 10.0 N;
(b) How does Hmax behave as F approaches zero and infinity, respectively?
(c) Evaluate the equilibrium height, Heq, for F = 10.0 N; and
(d) when F approaches infinity.
