A bicycle chain is wrapped around a rear sprocket (r = 0.039m) and a front sprocket (r = 0.10m). The chain moves with a speed of 1.4m/s around the sprockets, while the bike moves at a constant velocity. Find the magnitude of the acceleration of a chainlink that is in contact with (a) the rear sprocket, (b) neither sprocket, and (c) the front sprocket.

Question

How do I set this up to get the answers?

You are given tangential velocity. On the sprockets, acceleration is tangential velocity squared divided by radius.

Answer 1

a=v^2/r
