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 from 60 rpm to 92 rpm in 10 s. Assume constant angular acceleration. What is the tangential acceleration of a tooth on the sprocket? Express your answer with the appropriate units. ▾ View Available Hint(s) Hint 1. How to approach the problem Recall the relation between tangential acceleration and angular acceleration. Recall the definition of the latter to find its value. O Ti a = 1.86 μA m ?
