## Homework Statement

A 135 kg sled is being pulled along a horizontal surface at a uniform speed by means of a rope making an angle of 19.3 degrees with the horiontal. If the tension in the rope is 119 N Find the Coefficient of friction.

## Homework Equations

u=Ff/Fn

## The Attempt at a Solution

I have never done a question like this before but i fugured i probably had to find the force from the horizontal..im not sure if i did it right but i used trig to find that force and i got 112.3 N i then put that in the formula U=112.3/135 and i got 0.8319 but I really have no idea if i did it right.
