A cyclist starts from rest and pedals so that the wheels make 7.7 revolutions in the first 5.1 s. What is the angular acceleration of the wheels (assumed constant)?

  • Physics -

    (1/2)*alpha*t^2 = 2 pi * 7.7 radians

    alpha = 4 pi * 7.7/ t^2

    alpha is the angular acceleration in radians/s^2
