A skier starts from rest at the top of a hill. The skier coasts down the hill and up a second hill, as the drawing below illustrates.

The crest of the second hill is circular, with a radius of r = 37.3 m. 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?


Expert Answer

Step 1

The height of the first hill can be calculated in given steps.


Radius of circular hill, r = 37.3 m

Step 2


The centripetal force is balanced by the weight and the normal force. Thus, we have

Step 3

According to law of conservation of ener...
