You set a small eraser at a distance of 0.19 m from the center of a turntable you find In the attic and establish that when the turntable is turned on, the eraser travels In a circle with a constant tangential speed of 0.51 m/s. If your desk lamp projects a shadow of the apparatus on a wall which Is the same size as the real apparatus, determine the following for the oscillatory motion of the eraser's shadow. (a) period (b) amplitude m c) maximum speed m/s d) magnitude of the maximum acceleration m/s2
