Three seconds after a polisher is started from rest, small tufts of fleece from along the circumference of the 225-mm-diameter polishing pad are observed to fly free of the pad. If the polisher is started so that the fleece along the circumference undergoes a constant tangential acceleration of 4 m/s2, determine (a) the speed v of a tuft as it leaves the pad, (b) the magnitude of the force required to to free a tuft if the average mass of a tuft is 1.6 mg.
