I Finding Friction Force on a Break Pad

  1. May 17, 2017 #1
    A 30-cm-diameter, 1.6 kg solid turntable rotates on a 1.4-cm-diameter, 450 g shaft at a constant 33 rpm. When you hit the stop switch, a brake pad presses against the shaft and brings the turntable to a halt in 15 seconds.

    How much friction force does the brake pad apply to the shaft?

    I am struggling with answering this problem and I am not too sure how to approach it.
