Please answer it within 30 minutes.I will upvote! A skier is going down a hill at a constant speed in the downward direction. The skier’s mass is 70 ?? and the hill is at an angle of 30° with respect to the horizontal. Both surface friction and air drag are considered. What is the air drag force (in unit of N) along the direction of the velocity? Assume the kinetic coefficient of friction is 0.3; the gravity on the earth is 9.8 m/s2; cos(30 degree) is 0.866, and sin(30 degree) is 0.5. Round the answer to two decimal points. (You must use the numbers/constants provided here for the calculation)
