Work and Pulley

  1. May 16, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    W = Torque * distance

    3. The attempt at a solution


    The net torque is 8*.09-11*.06 = .06, and the distance moved is 4pi, because 2 full rotations, but this is not one of the choices...

    The question states that the amount of string unraveled is 1 m, not 2 m. (Oops, I did not see your second post.)

    Note that the torques act in the same direction.
