A skier (of mass 55 kg) skies down the smooth (frictionless) ski slope illustrated in the cross-sectional diagram. She pushes off at the top with a speed of 10m/s. At the bottom (0m), she comes to a stop by digging her skis in sideways. (the attachment goes here)
(c) Assuming that the snow at the point where she comes to a stop is at a temperature of 0 °C and that all of the kinetic energy of the skier goes into melting the snow, con- struct a complete Energy-System Diagram that can be used to predict the amount of snow melted by the skier while stopping. Substitute for constants and variables and identify any unknown(s) as in Part (a).*
*(a) Construct a complete Energy-System Diagram that can be used to predict the speed of the skier when she is on the middle flat part (at 10m). Substitute all known values of constants and variables, and identify any unknown(s). Do you have enough information to determine the speed at this part of the hill?
