A skier slides down along a frictionless snow slope starting from rest at point A with elevation hA = 84 m. Ignore air resistance.

(a) Find the speed of the skier at point B with elevation hB = 21 m and point C with elevation hC = 62m.

(b) Draw force diagrams of the skier at points A, B and C.

(c) If the mass of the skier is m = 63 kg and the radius of curvature at point B is RB = 50 m nd the normal force exerted by the snow slope on the skier at point B. Compare this to the usual value of the apparent weight of the skier?
