Answer:
W = 1600 J
Step-by-step 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
