The front and rear sprockets on a bicycle have radii of 8.40 and 4.91 cm, respectively. the angular speed of the front sprocket is 12.3 rad/s. determine (a) the linear speed (in cm/s) of the chain as it moves between the sprockets and (b) the centripetal acceleration (in cm/s2) of the chain as it passes around the rear sprocket.

Explanation:

It is given that,

Radius of the front sprockets,

Radius of the rear sprockets,

The angular speed of the front sprocket is 12.3 rad/s,

(a) Linear speed of the front sprockets,

Linear speed of the rear sprockets,

(b) Let is the centripetal acceleration of the chain as it passes around the rear sprocket.

`Hence, this is the required solution.
