Coefficient friction between a toboggan and the snow

[nasadall]

Homework Statement

Peter is pulling Paul who is on a toboggan, along a rough horizontal snow surface using a rope which makes an angle of 30ᵒ with the horizontal. Paul and the toboggan have a total mass of 40kg and the toboggan is moving with a constant speed in a straight line. Given the tension in the rope is 50N, find the coefficient of friction between the toboggan and the snow.

Homework Equations

Guys i don't have a clue on this one, I've been killing my head on it.

The Attempt at a Solution

this is what i tried:

Fx = Fcos 30^o
43.30127019

Fy = Fsin 60^o
43.30127019

That's how far i can go.

please help

Why did you use 60 degrees in your calculation of the vertical component of the applied force?

If the toboggan is not accelerating, what can you say about the forces involved?
