A box is given an initial push up a ramp that is inclined at angle $\alpha$ above the horizontal, and then allowed to slide freely up the ramp until it stops at a maximum height $H$, measured relative to the base of the ramp. The box's speed at the base of the ramp is $V$, and the coefficient of kinetic friction between the box and ramp is $\mu$.

Which of the following equations is a correct application of work and energy ideas, that could be used to solve for the maximum height $H$ the box reaches above its starting position?
