Question

Problem 6 Ski Jump
(a) A ski jump is at an angle above the horizontal. If you must clear a distance L to reach the other
side which is a height h above the jump, show that your minimum speed to reach the other side must be:
v
L
Cos 0
g/2
Ltan 0 h
(b) If the skier was on the Sun where gravity is (roughly) 25 times stronger than on Earth, how much
faster would they have to go?

Expert Solution

Step 1

Given:-

A ski jump is at an angle $θ$ above the horizontal. If you must clear a distance L to reach the other side which is a height h above the jump.

The figure shows that the motion of the ski as

Find:-

a) show that your minimum speed to reach the other side must be:

$v = \frac{L}{\cos (θ)} \sqrt{\frac{\frac{g}{2}}{Ltan (θ) - h}}$

b) If the skier was on the Sun where gravity is (roughly) 25 times stronger than on Earth, how much faster would they have to go?
