A skier starts from rest at the top of a hill. The skier coasts down the hill and up a second hill,The crest of the second hill is circular, with a radius of r = 38.5m. Neglect friction and air resistance. What must be the height h of the first hill so that the skier just loses contact with the snow at the crest of the second hill?Homework Equations
ke=1/2mv^2 and pe=mghe=pe+ke
The Attempt at a Solution
e=0 so pe =ke and h=(H-2r) and v^2=grso i found h=2r+r/2 and i got 96.25 m but its not right please help
