Question

A person is riding a bicycle, and its wheels have an angular velocity of 15.15 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 13.47 revolutions. How much time does it take for the bike to come to rest?

Answer 1

The time is

$$t=\frac{2\omega}{2\pi n}=0.36\text{ s}.$$
