A small ball is attached to the outer edge of a stereo record that is revolving on a turn-table at an angular speed of w=3.49 rad/s. The record has a radius of 0.152-meters. A light is shown onto the turn-table and the shadow of the ball is projected onto a screen. For the simple harmonic motion of the shadow, what is the magnitude of (a) its maximum velocity and (b) its maximum acceleration.
