A sphere if mass m is attached to one end of a rigid stick with negligible mass. the other end of the stick is fixed in place so that the sphere can move in a circular path of radius R. as shown in figure 1. the sphere is released from rest with the stick at an angle of 60 degrees from the vertical. derive an expression for the speed of the sphere when it is at point B, the bottom most point of the circular path.
