Answer:
20m
Step-by-step explanation:
The work done by the tractor is given by the formula:
work = force x distance x cos(theta)
where force is the applied force, distance is the distance moved by the object, and theta is the angle between the force and the direction of motion. In this case, we know the force and the work done, but we don't know the distance or the angle.
However, we can use the fact that the work done is also given by:
work = force x distance
We can rearrange this equation to solve for distance:
distance = work / force
Plugging in the values given in the problem, we get:
distance = 20,000 J / 1000 N = 20 meters
Therefore, the tractor moved the rock a distance of 20 meters
