Homework 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...

Edit: never mind, delete the thread. (I cannot find delete button)

Edit 2: Replaced with new problem, that I do need help with.
 
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.
 
Thanks, got it now!
