A person is riding a bicycle, and its wheels have an angularvelocity of +20 rad/s. Then the brakes are applied and the bike isbrought to a uniform stop. During the braking, the angulardisplacement of each wheel is +15.92 revolutions.
a) How much timedoes it take for the bike to come to rest?
b) What is the angular accleration (in rad/s^2) of each wheel?
