Question
A ball is tied to one end of a string. The other end of the string is held fixed. The ball is set moving around a vertical circle without friction, and with speed vi = (Rg)1/2. At what angle from the bottom should the string be cut so that the ball will then travel through the center of the circle on its way to the ground?
