After fixing a flat tire on a bicycle you give the wheel a spin. Its initial angular speed was 7.35 rad/s and it rotated 15.0 revolutions before coming to rest. What was the average angular acceleration? For what length of time did the wheel rotate?

  • Physics -

    a) 0 = (7.35)^2 + 2 a ( 94.2)
    a = - 0.287

    b) 0 = 7.35 + -0.287t
    t = 25.61 s
