Question

We have a 60 kg skier starts from rest at the top of a hill. the skier coasts down the hill and up a second circular hill as seen in the drawing. consider the situation where friction and air resistance is negligible and it just loses contact at the top of the second hill. what must the radius of the 2nd circular hill be such that the skier just loses contact at the top of the 2nd hill?

Answer 1

r = 36 m 

Hope it helps!!
