Final answer:
To find the value of the resultant force that moved a box a distance of 18 m with work done of 239 J, the formula F = W / d is used, where F represents the force, W is the work done, and d is the distance. The calculated force is approximately 13.28 newtons.
Step-by-step explanation:
The student is asking for the value of the resultant force acting on a box that has been moved 18 meters with a total work done of 239 joules (J). This is a typical problem in the physics domain, specifically dealing with work and force. To find the value of the resultant force, we can use the work-energy principle, which states that work is equal to the force multiplied by the distance over which the force is applied, assuming the force is constant and acts along the same direction as the displacement (W = F x d).
Given that the work done (W) is 239 J and the distance (d) is 18 m, we can rearrange the formula to solve for the force (F) thus:
F = W / d
F = 239 J / 18 m
F = 13.28 N
Therefore, the resultant force acting on the box during movement was approximately 13.28 newtons.
