A 49 kg skier skis directly down a frictionless slope angled at 11° to the horizontal. Choose the positive direction of the x axis to be downhill 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 1.4 m/s2, and (c) increasing at a rate of 2.8 m/s2. Use g = 9.81 m/s2.

Interactive Exercises 5.12: Applying Newton's Laws (Alpine Skier) An alpine skier-see Fig. 5.12.1-has total mass (including equipment) of m 75.0 kg and is skiing down a smooth slope that makes an angle of strong wind blows directly up the slope, which results in a force of 50.0 N acting on the skier opposite to his motion 30.0 to the horizontal. It is a windy day and a Interactive Figure 5.12.1: An alpine skier travels downhill. His motion is modeled as...
