## Homework Statement

A 40 kg block slides down a

__rough__incline of 35 degrees with a constant velocity. Find the frictional force acting on the block.

## Homework Equations

Fgx = Fg sin theta

Fgy = Fg cos theta

Fg = mg

## The Attempt at a Solution

Well I drew a diagram and solved for my Fgx component and my Fgy component:

Fgx = 40(9.8)sin35 = 224.8 N

Fgy = 40(9.8)cos35 = 321.1 N

Now what do I do? Take the sum of Fx ? Won't that just be 224.8 N ? That doesn't sound correct I'm confused. Am I doing something wrong?
