A man is riding a racing bike, and its wheels have an angular velocity of +23.5rad/s. Then, the brakes are applied and the bike is brought to a uniform stop. During braking, the angular displacement of each wheel is +13.5 revolutions.
(a) Find how much time does it take for the bike to come to rest?
s
(b) Find what is the angular acceleration of each wheel?
rad/s2
