Answer:
56N
Explanation:
Given parameters:
Distance = 40m
Work done = 2240J
Unknown:
Force exerted = ?
Solution:
The work done on a body is the force applied to move a body through a certain distance.
Work done = Force x distance
Now insert the parameters and solve for the force
2240 = Force x 40
Force = 56N
