## Homework Statement

A roof has an incline of 10 degrees. If the µ of friction between a 50kg box and roof is .15, how fast will the box move?

## Homework Equations

Ff=µ * Fn

## The Attempt at a Solution

I have no idea how to get this. I know it very easy.

I figured out Fg = 490N (Fg=9.8 * 50kg)

I figured out Fn = 482.56 (Fn=490 cos 10)

I figured out F//=85.09 (F//=490 sin 10)

I figured out the Acceleration with no friction is 1.70 m/s

^{2}85.09/50

Any help is appreciated, thanks
