Answer:
F= 56 N
Explanation:
Work theory
Work is the product of a force applied to a body and the displacement of the body in the direction of this force.
W= Fd Formula (1)
W: Work (Joules) (J)
F: force applied (N)
d=displacement of the body (m)
The work is positive (W+) if the force goes in the same direction of movement.
The work is negative (W-)if the force goes in the opposite direction to the movement
Data
W==2240 J
d= 40m
Problem development
We apply the formula (1)
W= Fd
2240J= F 40m
F = 2240 Nm / 40m
F= 56 N
