The wheels of a bicycle have an angular velocity of 20.0 rad/s. Then, the brakes are applied. In coming to rest, each wheel makes an angular displacement of 15.92 revolutions. (a) How much time does it take for the bike to come to rest? (b) What is the angular acceleration (in rad/s2 ) of each wheel? *
