shawonna23

The front and rear sprockets on a bicycle have radii of 9.00 and 5.10 cm, respectively. The angular speed of the front sprocket is 8.60 rad/s.

(a) Determine the linear speed (in cm/s) of the chain as it moves between the sprockets.
cm/s
(b) Determine the centripetal acceleration (in cm/s2) of the chain as it passes around the rear sprocket.
cm/s2
