Homework Statement
A 50kg skier skis directly down a frictionless slope angled 16* to the horizontal. Assume the skier moves at a negative x direction. A wind force with component Fx acts on the skier.
What is Fx if the skier's velocity magnitude is constant?
Homework Equations
The Attempt at a Solution
I really have no idea. I assume Fx is equal to the force the skier exerts "on the air" so F = ma on the skier.
But I am utterly confused when they say velocity is constant. He is going down the slope due to gravity, how could his velocity be constant? It makes no sense to me.
