Answer:

W = 1600 J

Explanation:

Given in the question,

force exerted = 400N

distance it covered = 4m

The general formula for work and for determining the amount of work that is done on an object is:

W = F × D × cos(Θ)

The SI unit for work is the joule (J)

Plug values in the formula

W = 400(4) cos(0)

W = 400(4)(1)

W = 1600 J
