For this question I need to develop a strategy for solving the problem.

a 75.0 kg cross country skier is climbing a 3.0 degree slope at a constant speed of 2.00 m/s and encounters air resistance of 25.0 N. Find his power output for work done against the gravitational force and air resistance. (b) What average force does he exert backward on the now to accomplish this? (c) if he continues to exert this force and to experience the same air resistance when he reaches a level area, how long will it take him to reach a velocity of 10.0 m/s?

#### Top Answer

(a) Power output of skier is given by, P = 127 W (b)... View the full answer
