A skier is going down a hill (we will assume it is frictionless). The x-axis is parallel to the hill, and the y-axis is perpendicular to the hill. The skier's mass is 50 kg and the hill is at an angle of 30∘ above the horizontal (this will also be the angle between the y-axis and the weight force). Determine the normal force on the skier and the skier's acceleration. Use g = 10 m/s2 for this problem. 483 N and 5 m/s2 483 N and 6.7 m/s2 None of the others 433 N and 5 m/s2 433 N and 50 m/s2
