The swing shown consists of a vertical central shaft with a horizontal arm attached at its upper end. The arm supports a load suspended from a cable being fastened to the arm 4.5.00 m at a point 4.00 m from the central shaft. (see Figure) 4.00 m The swing rotates once in 6.60 seconds. a) find the velocity of the swing as it turns around the shaft b) Find the angle 0 the swing makes with vertical. c) Does the angle depend on the weight of the load for a given rate of revolution?
