Answer:
d = 3.6 m
Explanation:
The formula for Work: W = F * d
Where F is force in Newtons (N) and d is the distance travelled in meters (m). In order to do work, you need to force an object throughout a distance.
That's why pushing a wall (that doesn't move) is not considered work, because you can't move the wall to a distance.
So what we know:
F = 5,000 N
W = 18,000 J
d = W / F (according to the formula, right?)
d = 18,000 / 5,000 = 3.6 m
