# Finding coefficient of friction given slope

## Homework Statement

A skier coasts down a 3.5 degree slope at a constant speed. Find the coefficient of kinetic friction between the skis and the snow covering the slope.

## Homework Equations

coefficient of friction x Normal force = force friction

therefore: coefficeint of friction = force friction / normal force

## The Attempt at a Solution

I'm totally stuck. I drew the Free Body Diagram, but i have no idea where to go from there.

Well what is the force parallel to the slope and what is the force normal to the slope?

i wasnt given any of that information, the only other thing i know is that Fn=-Fg, since there is no accel, so the Ffr= (9.81)μm... but where do i go from there?

You need to split the weight into two components, one parallel to the slope and one normal to it.

The one normal to it will be your normal force which will give you the frictional force.
