Question:

A 40 kg skier skis directly down a frictionless slope angled at l-0o to the horizontal. Assume the skier moves in the negative direction of an x axis along the slope. A wind force with component Fx acts on the skier. What is Fx if the magnitude of the skier's velocity is

(a) Constant,

(b) Increasing at a rate of 1.0 m/s2, and
