A 55-kg skier skies down the smooth (frictionless) ski slope illustrated in the diagram. She pushes off at the top with a speed of 10 m/s. At the bottom (0 m), she comes to a stop by digging her skis in sideways. a) Construct a complete Energy-Interaction diagram to predict the speed of the skier when she is on the middle flat part (10 m). b) Repeat a) to find the speed of the skier at the bottom of the hill (before she starts stopping). c) Assuming that the snow where she comes to a stop is at a temperature of 0C, and that all of the kinetic energy of the skier goes into melting the snow, construct a complete Energy-Interaction diagram to predict the amount of snow melted by the skier while stopping. d) Choose a different interval from the one you used in b), and solve again for the amount of snow melted when the skier stops. Is your answer the same as in b)?
