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] = 1/2mv2 + 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.
