An 16-cmcm-long bicycle crank arm, with a pedal at one end, is attached to a 22-cmcm-diameter sprocket, the toothed disk around which the chain moves. A cyclist riding this bike increases her pedaling rate from 61 rpmrpm to 95 rpmrpm in 10 ss .

A. What is the tangential acceleration of the pedal? Express your answer to two significant figures and include the appropriate units.

B. What length of chain passes over the top of the sprocket during this interval? Express your answer to two significant figures and include the appropriate units.
