Chapter 8, Problem 5P
A light, rigid rod is 77.0 cm long. Its top end is pivoted on a frictionless, horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speed at the bottom is required to make the ball go over the top of the circle?

In the figure, a solid 0.3 kg ball rolls smoothly from rest (starting at height H = 6.4 m) until it leaves the horizontal section at the end of the track, at height h = 1.5 m. How far horizontally from point A does the ball hit the floor?
The answer is not 5.42.
