  1. Sorry, cant do it, but I will turn it over in my mind


  2. This is just a T = Inertia * angular acceleration problem.

    Your angular acceleration is derived from the steady state angular velocity and the time to decelerate.  Then, derive the torque resultant from the required angular acceleration.
