PROBLEM 12.93 A small ball swings in a horizontal circle at the end of a cord of length 4, which forms an angle 6, with the vertical. The cord is then slowly drawn through the support at O until the length of the free end is . (a) Derive a relation among 4, ½, 0,, and 0,. (b) If the ball is set in motion so that initially 4 =0.8 m and 6, =35°, determine the angle 0, when , =0.6 m.
