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...
A 63 kg skier skis directly down a frictionless slope angled at 20° 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. (Indicate the direction with the sign of your answer.) (a) What is Fx if the magnitude of the skier's velocity is constant? N (b) What is Fx if the magnitude of the skier's velocity is increasing at a rate...
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.
••28 A 40 kg skier skis directly down a frictionless slope angled at 10° to the horizontal. Assume the skier moves in the negative direction of an x axis along the slope. A wind force with component F, acts on the skier. What is F, if the mag- nitude of the skier's velocity is (a) constant, (b) increasing at a rate of 1.0 m/s2, and (c) increasing at a rate of 2.0 m/s??
A 65.0-kg skier is skiing down a 35.0o slope. If the friction force on her ski is 32.0N, what is her acceleration down the slope? Answer: m/s2 What is the normal force on the skier?
A 70- kg skier slides down a frictionless slope which forms a 30° angle above horizontal. Calculate the normal force and the acceleration of the skier.
A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 degrees with the horizontal. The rope moves parallel to the slope with a constant speed of .0m/s. The force of the rope does 900J of work on the skier as the skier moves a distance of 8.0m up the incline. (a) If the rope moed with a constant speed of 2.0m/s, how much work would the force of the rope do on...
You go skiing down a smooth, frictionless slope, which is at an angle of 15◦ relative to the horizontal. What is your acceleration down the slope?
A skier speeds down a smooth ski slope which is at an angle of e 20° with the horizontal. The mass of the skier is 61 kg. Take the downhill direction to be positive and uphill to be negative.
