In this problem, we are given a force-distance curve. We are also required to apply the work-energy theorem. In a force-distance graph, we know that work done by the force is equal to the area under the graph.
We'll determine the force at 5m. The graph does not show the position of 5. We'll subdivide the length between 4 and 8 to estimate the location of 5m. We'll also estimate the amount of force, then work out the area under the curve.
