Question
A sled is pulled at a constant velocity across a horizontal snow surface. If a force of 100 N is applied to the sled at an angle of 40 degrees to the ground, what is the force of friction between the sled and the snow?

For equilibrium in the horizontal direction,
Frictional force = Fcos(θ)
Frictional force = Fcos(θ)
