A person is riding a bicycle, and itswheels have an angular velocity of +25.0 rad/s. Then,the brakes are applied and the bike is brought to a uniform stop.During braking, the angular displacement of each wheel is+11.0revolutions.
(a) How much time does it take for the bike tocome to rest?
(b) What is the angular acceleration of each wheel?
