Answer 1

Zero work

Step-by-step explanation:

Recall that work done on an object is defined as the product of the net force applied to an object times the distance it travels in the same direction as the force.

Since in this case Jim used a given force to push a rock, but it didn't move, then he did zero work (because the distance moved is zero).
