A person with a mass of 200kg wearing snow skis is gliding down a long slope at an angle of 20 degrees. Each ski is 200cm long and 5 cm wide. The pressure of the skis on the snow melts a thin layer of water so that a .1mm layer of water exists under each ski. The water layer is at a temperature of 0C. Determine the maximum velocity that the skier will achieve without using poles. Neglect the drag force of the air on the skier.
