I need to calculate the work done by an electric motor when it has a pulley wheel on the end but nothing on the pulley wheel. I know work done = force x distance. And of course force = mass x acceleration. But I cannot for the life of me think of how I am going to work out the acceleration? or the distance. Normally the distance is the distance of the object being pulled by the motor..but my motor isn't pulling anything over a distance.

How do i get the acceleration for F and how do i get the distance?
Thanks
