Q. A stunt man whose mass is 70 kg swings from the end of a 4.40-m long rope along the arc of a vertical circle. Assuming that he starts from rest as rope is horizontal, find out the tensions in the rope that are required to make him follow his circular path at each of the following points.

(a) At the beginning of his motion

(b) at a height of 1.5 m above the bottom of the circular arc

(c) at the bottom of the arc
