A bicycle chain is wrapped around a rear sprocket (r = 0.037 m) and a front sprocket (r = 0.06 m). The chain moves with a speed of 1.2 m/s around the sprockets, while the bike moves at a constant velocity. Find the magnitude of the acceleration of a chain link that is in contact with each of the following.

Question

a.) the rear sprocket ________ m/s^2
b.) neither sprocket __________ m/s^2
c.) the front sprocket ________ m/s^2
