After Successfully summiting a mountain, 72.0 kg climber is standing on a slope of angle 28 degrees, The frictional coefficients between her and the mountain slope are us=0.770, uk=0.280. a) At first, the climber does not exert a push on the ground to get herself moving, and therefore she remains stationary. What is the force of friction that she experiences in this situation? b) Then, the climber pushes off down the slope, with sufficient force to overcome static friction. What is the magnitude of that force? c) Once the climber has done the initial push off, she is no longer pushing, but begins sliding down the slope under her own weight. Draw a free body diagram for that situation. d) Find the climber's weight, the normal force, and the force of friction she experiences while moving
