Step-by-step explanation: make brainalist and keep smiling

First, recall the definition of work. The work done by a constant force is equal to the force multiplied by a displacement

s:W=F⋅s

If the work done was 55,000 Joules, and the displacement traversed was 25 meters, then all you need to do is substitute into the equation:

55,000J

=25m⋅F

Divide both sides by 25 meters to solve for

F

:

55,000

J25m=F

Since the Joule is defined as Newtons multiplied by meters, the meters will cancel off, and our answer will be:

F=2,200N
