A bicycle wheel slows down uniformly to rest over a ditance of 45 m becuase the bicyclist sees something int he road ahead. Initally, a point out of the outside of the wheel is traveling at 8.0 m/s, and the wheel is 68 cm in diamtere.

a) What is the wheels inital angular velocty?

b) How many revolutions does the wheel make before comming to a stop?

c) Whats the angular acceleration of the wheel?

d) How long did it take to stop?
