Answer to Question #180784 in Physics for Andu

Question

The skier with mass m = 80kg climbs 400m with telescope on the track, which forms the angle a = 30⁰ with the horizontal direction. On the skier, through the telescope, the force F = 700N is exerted, which forms the angle fi = 45⁰ with the track. The friction force that the snow exerts on the skier is f = 50N. Find: a) The work done by each of the forces acting on the skier. b) General work performed on the skier. (g = 10m / s)
