Solve part A & B

3. A skier skies down and up frictionless slopes (A and C) however across the flat ground (B) from A to C with friction (H = 0.1) from rest (see the diagram below). The mass of the skier is m = 84 kg. A C h, = 214 m h, = 214 m 8, = 30' B 8, = 60' d = 43 m (a) Determine the skier's speed at the bottom of A and at the end of B. What height does the skier reach along C? (b) Identify all of the forces acting on the skier in each of the regions listed above. What is the work done by each of these forces in these regions? Make a table and present your calculations neatly. Include units
