A skier starts from rest at the top of a hill. The skier coastsdown the hill and up a second hill, as the drawing illustrates. Thecrest of the second hill is circular, with a radius of r =33 m. Neglect friction and airresistance. What must be the height h of the first hill sothat the skier just loses contact with the snow at the crest of thesecond hill?
