A person with a mass of 85 kg wearing snow skis is gliding down a long slope at an angle of 15 degrees. Each ski is 185 cm lonf and 10 cm wide. the pressure of the skis on the snow melts a thin layer of water o that a 0.1 mm layer of water exists under each ski. The water layer is at a temprature of 0 C. Determine the maximum velocity that the skier will achieve without using poles. Neglect the drag force of the air on the skier.
