Ski jumpingClassical Mechanics Level 5
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 \(\mu\) 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 air resistance.
- The acceleration of gravity is \(-9.8~m/s^2\).
- The hill slopes down at an angle of \(\theta=30^o\) below the horizontal.
- The skier started from rest at the top of the jump.
