## Homework Statement

- An inclined plane is used to raise a 100 kg box to a height of 5 m. How long must the inclined plane be if a force of 250 N is used to push the box up the inclined plane?

## Homework Equations

i have search and searched all over google to try to figure this out.. I am not sure if I'm over thinking it or just confused myself even more. I found one equation that I think is correct, but as i was looking at other examples I tried to use this formula and it never worked out like I thought it should. Also, I am always finding examples that have an angle of inclination.. But the formula I think should work is.

[tex]\frac{f}{w}=\frac{h}{l}[/tex]

## The Attempt at a Solution

[tex]\frac{250}{100}=\frac{5}{l}[/tex]

l=2???

cheers
