Bond starts from rest and glides down the slope. At the bottom of the hill, Bond continues to ski on a flat section. Calculate how fast Bond will be moving on this flat part if the hill is 100 ft. higher than the flat area. Additionally, include how changing the hill so that it is less steep, but still starting Bond 100 ft. higher than the flat area will affect Bond's velocity at the bottom. Bond is using new, top-secret FRICTIONLESS skis.
