## 2. One Rule Aerial Skiers Cannot Break

January 23, 2014Aerial skiers aim for height rather than length. Their aerial flight times are much smaller than ski jumpers so air resistance has minimal impact.

In fact, there is one law the aerial skiers cannot break. It is the law of gravity.

Here is an equation for projectile motion from Wired magazine.

Here is the x-y graph for different launch angles.

You can go to this page for complete calculations. Aerial skiers twist and turn but their CENTRE OF GRAVITY must follow this graph. MOre on centre of Gravity at The Great Back Pack Attack ie.

The centre of gravity of Aerial Skiers must follow a

# parabolic curve.

Good morning,

I am publishing a book on quadratic equation. I would like to use one of your pictures – the first picture with aerial skier – in my book to motivate students’ learning.

Please let me know if you are agreeable to this. I can be contacted at my.quadratic@gmail.com

Best regards,

Thinh Le, Ph.D.

Hello Thinh Le, I would be delighted if you used one of my diagrams. The source of that picture, however, is not clear. I found it on a blog. So that’s a yes/no answer I’m afraid. Cheers Mathspig
