•38 A 40 kg skier skis directly down a frictionless slope angled at 10° to the horizontal. Assume the skier moves in the negative di- rection of an x axis along the slope. A wind force with component F, acts on the skier. What is F, if the magnitude of the skier's veloc- ity is (a) constant, (b) increasing at a rate of 1.0 m/s², and (c) in- creasing at a rate of 2.0 m/s²?
