Jim did no work because the rock did not move.
Explanation:
The equation of work is that work is equal to force multiplied by distance. So how much work has been done by a particular person is seen by the amount of force that has applied by the person into the distance that has been covered.
In the question given above, since force has been applied by Jim but the rock did not move at all. It did not cover any distance. So therefore the work done by Jim was zero.
