## Homework Statement

A person is riding a bicycle, and its wheels have an angular velocity of +22.0 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 +11.0 revolutions.

(a) How much time does it take for the bike to come to rest?

s

(b) What is the angular acceleration of each wheel?

rad/s2

## Homework Equations

theta = (angular velocity)(time)

## The Attempt at a Solution

11=22t

11/22 = t=1/2

thats wrong i guess.

can you help me out?
