A constant force $F$, acting on a car of mass $m$, moves the car up a slope through a distance $s$ at constant velocity $v$. The angle of the slope to the horizontal is $\alpha$. What is the ratio $\dfrac{\text{gravitational potential energy gained by car}}{\text{work done by force } F}$?

1. A$\dfrac{mgs\sin\alpha}{Fv}$
2. B$\dfrac{mv}{Fs}$
3. C$\dfrac{mv^2}{2Fs}$
4. D$\dfrac{mg\sin\alpha}{F}$
