When a 60 kg skier first starts to be pulled up the ski hill by an old school T-bar, she undergoes a constant acceleration of 1.8 m/s2 during the first few seconds of the pull. The applied force from the T-bar is directed 40 degrees above a line that is parallel to the surface of the hill The incline of the hill is 19 degrees above the horizon, as can be seen by alpha in the figure below. Assume that the positive X direction is directed up the hill and the positive y direction is directed away from the surface of the hill and that the coefficient of dynamic friction between the skiis and the snow is 0.1.

a) What is the magnitude of the applied force (FApp) in Newtons (N) required from the T-bar when the skier first starts to be pulled up the hill with a constant acceleration of 1.8 m/s2?
b) What is the magnitude of the normal force between the skier and the snow in Newtons (N) in the scenario described above (skier is being pulled up the hill by the T-bar with a constant acceleration of 1.8 m/s2)?
c)
