An 18-cm-long bicycle crank arm, with a pedal at one end, is attached to a 20-cm-diameter sprocket, the toothed disk around which the chain moves. A cyclist riding this bike increases her pedaling rate form 60 rpm to 90 rpm in 10 s.

a. What is the tangential acceleration of the pedal?

b. What length of chain passes over the top of the sprocket during this interval?
