1. The problem statement, all variables and given/known data 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. 2. Relevant equations I'm not sure but I believe this one(?): WƩF=ΔEk 3. The attempt at a solution Well...as I said I was trying to find it with the equation of WƩF=ΔEk but it doesn't seem to be relevant... I was also trying to use the graph, yet I have no idea how to reach the answer with it. Thanks in advance.
