When a ceiling fan rotating with an angular speed of 1.65 rad/s is turned off, a frictional torque of 0.263 N·m slows it to a stop in 4.75 s. What is the moment of inertia of the fan?

  • Physics -

    First get the angular deceleration rate, alpha, using
    alpha * 4.75 s = 1.65 rad/s
    alpha = 0.347 rad/s^2

    Then use Torque = I * alpha

    Solve for I. You know the torque T already
