4-A wheel of rotational inertia, I = 4 kg-m about its fixed central axis has an initial angular velocity, wi = 9 rad/s at t = 0. Its angular acceleration is, a = 3 rad/s. Find: (a) the angular velocity of the wheel at t = 2 s. What is the angular displacement (AO) of the wheel during the 2 s. (b) Find the net torque acting on the wheel. What is time rate of change of the angular momentum? 4-A wheel of rotational inertia, I = 4 kg-m about its fixed central axis has an initial angular velocity, wi = 9 rad/s at t = 0.
