A bicycle chain is wrapped around a rear sprocket (r = 0.041 m) and a front sprocket (r = 0.15 m). The chain moves with a speed of 1.4 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.

(a) the rear sprocket
m/s2
(b) neither sprocket
m/s2
(c) the front sprocket
m/s2
