A 30-kg toboggan made of birch wood is facing downhill on a well-packed snowy slope. At a location where the slope is 25.0° , the toboggan just begins to slide downhill. What is the coefficient of static friction for the birch toboggan on packed snow?

mgsin $\theta$θ =FS
mgcos $\theta$θ =N
FS= $\mu$μS.N
mgsin $\theta$θ = $\mu$μS .mgcos $\theta$θ
$\mu$μS = $\frac{sin\theta}{cos\theta}$sinθcosθ = Tan (25)
