The graph shows the force exerted on an object versus the position of that object along the x-axis. The force has no components other than along the x-axis. If z is an increment of 25, then what is the work done by the force on the object as the object is displaced from 0 to 3 m?

Answer 1

Again, we do not see the graph. However, if the graph is force versus distance, the area of the graph from distance =0 to 3 will give the work done. Be careful with the units, which you can find from the graph's axes.
