A person is riding a bicycle, and its wheels have an angularvelocity of +18.5rad/s. Then, the brakes are applied and the bike is brought to auniform stop. During braking, the angular displacement of eachwheel is +11.5revolutions.
(a) How much time does it take for the bike tocome to rest?
s
(b) What is the angular acceleration of each wheel?
rad/s2
