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 don't 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.
When they mention "two possible outcomes of the work done," they are referring to the effects that the work done by the force could have on the object. In physics, work is defined as the product of the force applied on an object and the displacement of the object in the direction of the force.
To calculate the work done at each displacement listed, you would need to use the formula:
Work = Force * Displacement * cos(theta)
Where theta is the angle between the force and displacement vectors. Without knowing the exact values of the displacements, forces, and the angles involved, it is not possible to determine the specific outcomes or effects that the work done could have on the object.
However, based on the values you provided for the work done (a = 160J, b = 200J, c = 480J), we can make some general assumptions about the possible outcomes:
1. If the work done is positive (e.g., 160J or 200J), it means that the force and displacement have the same direction, and the object is gaining energy. This could result in the object moving faster or increasing its kinetic energy.
2. If the work done is negative (e.g., -480J), it means that the force and displacement have opposite directions. In this case, the object is losing energy, which could result in the object slowing down or decreasing its kinetic energy.
Please note that these assumptions are based on the general principles of work, and the specific effects on the object would depend on the nature of the force and the object itself. Without the graph and more information, it is difficult to provide a more detailed analysis.
