A person is riding a bicycle, and its wheels have an angularvelocity of 22.0 rad/s. Then, the brakes are applied and the bikeis brought to a uniform stop. During braking, the angulardisplacement of each wheel is 12.9 revolutions. (a) How much timedoes it take for the bike to come to rest? (b) What is the anguaracceleration (in rad/s2) of each wheel?
