Homework Help: Angular Momentum

  1. Aug 2, 2011 #1
    1. The problem statement, all variables and given/known data

    I've uploaded a pic of the problem and my work at the link below:


    2. Relevant equations

    I = mR^2 w

    Hopefully everything thus far is correct, I'm stuck at finding the rate of change. From what I understood it's essentially the derivative of Angular Momentum with respect to time. Thank you in advance.

    The rate of change of angular momentum is torque, or the moment of inertia multiplied by angular acceleration.

    Thank you Pi-Bond. Does my approach for getting the angular momentum appear to be correct?

    Yes, that appears to be correct.
