Work energy problem with damping?

  1. Dec 9, 2012 #1
    1. The problem statement, all variables and given/known data
    I need help with part d.

    3. The attempt at a solution
    I worked out the damping constant and I am pretty sure it is correct. So I tried to solve this using work energy theorem. I ended up with a quadratic equation and solved for two solutions. None of them match the answer key which is -0.081rad/s. What am I doing wrong? Is the energy term for the damper correct?

    Essentially I have:
    Spring energy + Gravitational energy = Work done by damper + Rotational kinetic energy of the whole system
