A bicycle chain is wrapped around a rear sprocket (r = 0.038 m) and a front sprocket (r = 0.11 m). The chain moves with a speed of 1.6 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 (b) neither sprocket (c) the front sprocket
