The “Giant Swing” at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. Each arm supports a seat suspended from a cable 5.00 m long, and the upper end of the cable is fastened to the arm at a point 3.00 m from the central shaft. (a) Find the time of one revolution of the swing if the cable supporting a seat makes an angle of 30.0∘ with the vertical. (b) Does the angle depend on the weight of the passenger for a given rate of revolution?
(A) Time period T = 6.189 sec
(B) Angle is independent of weight.
