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

You're pushing a car up an inclined plane (a hill). Which graph matches the relationship between ∆x and v?

2. Relevant equations

W = K.E. + P.E.

thus: F∆xcos[itex]\theta[/itex] = 1/2mv^{2}+ mgh

3. The attempt at a solution

The answer is C. I thought the answer was D - I don't understand why the relationship is a negative. Please share an explanation with me.
