DRWLS: PLEASE SEE ADDITIONAL INFO AT THE BOTTOM

its the second part of the question that I don't understand:

according the graph shown, the net force acting on an object varies wth the object's displacement. Calculate the work down by the force on the object at the various displacements listed below (i won't bother telling you since you don't have the graph, but I figured out the work done to be these)

a)the work done = 160J
b)200J
c)480J

"state two possible outcomes of the work above being done on the object". I dont know what they mean by that...

Please explain!

Maybe they mean for two of the different displacements. Without seeing the complete question and figuree, it is hard to say.

yes, that is what they mean...two possible outcomes of the work done, based on the displacements. What do they mean by "outcome" though? No times are given in the graph, so I can't figure out the power outputs...Only forces and displacement were given in the graph.

outcome could be final kinetic energy, an increase in potential energy, or an increase in friction generated heat.
