A cord is wrapped around a pulley of diameter 0.320 mwith the free end tied to a weight. That weight is allowed todescend at constant acceleration. A stopwatch is started at theinstant when the weight reaches a speed of 0.023m/s. At a time of t = 1.50 s, the weighthas dropped an additional 0.080 m. Calculate the magnitudeof the centripetal acceleration of any point on the circumferenceof the pulley at t = 4.0 s.
Calculate the magnitude of the tangential acceleration of anypoint on the circumference of the pulley.
