(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In an experiment, one of the forces exerted on a proton is F=<-ax^{2},0> where a =12N/m^{2}. Calculate the work done by this force as the proton moves along a straight-line path from the point r_{i}=<0.10m,0> to the point r_{f}=<0.30m, 0.40 m>

2. Relevant equations

I'm not sure if I would use W=F*change in x (don't know how to type in the delta symbol) since it says it's a straight line path, or if I would use W=F*change in r since the problem contains r's in it

3. The attempt at a solution

I'm not too sure what to do here. I see that I'm given a F_{x}and F_{y}but I don't know exactly what to do with the multiple r's. Thanks for any help!
