Yes, it is a graph of the net Force vs. displacement.
Sorry for not mentioning it, but I already found the work of the net Force(48J).
How can I answer where(I think my teacher was mistaken)?
No, there's another question to find the mass of the body and it's after this question so it's not...
I wrote voltage instead of velocity...No idea why. And yes, Ek stands for kinetic energy. Can you/anybody else please help with my question(when does the velocity get zeroed?). Thanks
Homework Statement
Basically, I was given this graph: http://i48.tinypic.com/qrdabs.png
In addition I was asked to find out what's the work of the net force between x=0m and x=6m.
Homework Equations
I'm not sure but I believe this one(?): WƩF=ΔEk

Well...as I said I...
