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 5.00{\rm m} -long cable, the upper end of which is fastened to the arm. take r = 2.10{\rm m}find the time of one revolution of the swing if the cable supporting the seat makes an angle of theta = 28.0^\circ with the vertical. does the angle depend on the weight of the passenger for a given rate of revolution?
