Re: Ridiculous x-games fall
[ QUOTE ]
Wow...He could have been seriously hurt, but that was a good fall. When it's in slow motion near the end of the video you can see his feet hit first, then he lands on his back...That's about the best you can hope for in that situation. [/ QUOTE ] This is totally wrong. The curve helped him, but the best way to land in a fall like that is to hit the ground rolling, preferably shoulder first.

Re: Ridiculous x-games fall
I thought for sure that his legs were broken when he fell.
Sick.

We might as well calculate this out: A basic equation of one-dimensional motion is Vf^2 = Vi^2 + 2ad. Plugging in 0 as Vf, -9.8 for a and 15 for d, I get 12 meters per second for Vi, which is in the neighborhood of 27 mph. In any case, it's still too fast to get a running landing off of the board. [/ QUOTE ] You forgot the "2" in "2ad" then you did the calculation. No big deal though.

[ QUOTE ] [ QUOTE ] [ QUOTE ] I don't know if that's a great situation--where would you go? If he made it 50 feet into the air he must have hit the quarter-pipe at a good clip--at least 25 mph or so. [/ QUOTE ] 40 mph, absolute minimum. [/ QUOTE ] We might as well calculate this out: A basic equation of one-dimensional motion is Vf^2 = Vi^2 + 2ad.

[/ QUOTE ] This isn't right. It's ~40mph. Ep = Ek mgh = 1/2mv^2 2gh = v^2 v = (2gh)^0.5 v = (2 * 32 * 50)^.5 = 56.5 ft/s 56.5 ft/s = 38mph edit: your equation was fine (same as mine, really), your calculation was wrong. [/ QUOTE ] Oops, yup, you were right. I forgot the last part was 2ad, not ad.
