Question #24537

A ski jumper launches from a ski jump that is oriented parallel to a hill. The jump has a vertical drop of 50 m and the coefficient of friction μ between the skier and the jump is 0.05. The launch point is 5 m above the hill and there is a small lip at the bottom of the jump so that the skier launches horizontally. How long in seconds is the skier in flight?

Details and assumptions

Neglect friction and air resistance.

The acceleration of gravity is −9.8 m/s^2.

The hill slopes down at an angle of θ=30 below the horizontal.

The skier started from rest at the top of the jump.
