What length of time did the wheel rotate

Reference no: EM13663055

After fixing a flat tire on a bicycle you give the wheel a spin.

a) If its initial angular speed was7.01 rad/s and it rotated 15.0 revolutions before coming to rest, what was its average angular acceleration? (Consider speeding up positive and slowing down negative.)

b) For what length of time did the wheel rotate?
