The net force along the linear path of a particle of mass 320g has been measured at 13.0cm interval, starting at x=0.0, to be 26.0, 28.4, 28.8, 29.6, 32.4, 40.1, 46.6, 42.2, 48.8, 55.7, 55.8, 60.2, 63.0, 58.2, 53.7, 50.3, 45.6, 42.4, 43.2, 38.9, 35.1, 29.4, 27.2, 21.0, 23.9, and 18.6, all in newtons.

Determine the total work done on the particle over this entire range.

I got the answer work=5.2j but it's wrong, can anyone show me the steps? Thank you.

Welcome to Physics.SE. Our policy on homework-like questions is that we do not work basic exercises such as this. We will, however, answer very basic questions on physics concepts. I'm going to close this question for the moment, but it can be fixed and re-opened. – dmckee Oct 10 '12 at 4:19
To fix this you need to edit it to reflect the conceptual problem that you are having. I suspect that it revolves around the "right" way to evaluate a discretized integral. That is how much $F$ to use over the distance between each measurement. In actuality there is no unique answer, so it would also help if you told us how you tried working the problem. – dmckee Oct 10 '12 at 4:22
