A polisher is started so that the fleece along the circumference undergoes a constant tangential acceleration of 5 m/s 2. Five seconds after a polisher is started from rest, small tufts of fleece from along the circumference of the 250-mm-diameter polishing pad are observed to fly free of the pad. At this instant, determine (a) the speed v of a tuft as it leaves the pad, (b) the magnitude of the force required to free a tuft if the average mass of a tuft is 1.5 mg.

Five seconds after a polisher is started from rest, small tufts of fleece from along the circumference of the 250-mm-diameter polishing pad are observed to fly free of the pad. At this instant, determine (a) the speed v of a tuft as it leaves the pad, (b) the magnitude of the force required to free a tuft if the average mass of a tuft is 1.5 mg.
