A wonderfully executed hoax, or....? :-)
« on: May 08, 2010, 02:02:59 PM »
You can almost believe it's true.

A healthy man weighs 75kg, and can produce a over 1300W for about a dozen seconds. Some amphibians run over the water everyday. Bugs can stand on the water, all day. Why couldn't man in special shoes take a short sprint over it?

Well, it says the video was removed for terms of use violation, but I have attained a power of 1500 watts before, on a stationary bicycle, weighing 80 kilograms, and yet I can't run on water.

But it DOES remind me of something. Watch this:

I got a gadget as a gift once, a ball that bounces on water. Special urethane texture, density and flexibility. Stupid me managed to misplace it before I got to use it.

Still, it would be interesting if someone managed to calculate how hard one would need to kick the water, to keep a grown man from going under.

If someone MANAGED to calculate it? Why don't you just do it yourself if you're interested? Too lazy to find out the viscosity of water, or an approximation to the Reynolds number of, say, the bottom 6 inches of a human foot? Which brings up a problem with your statement of the problem. "going under"? How FAR under is under? If 6 inches is your limit, you will get a completely different answer from if your limit is 3 inches or a foot or a millimeter. Not just completely different answers, but the way the problem itself is solved will be completely different.

in fact I would submit (humbly) that Sandor be the one to calculate it.
As an exercise.
OR,,will he put us under his contempt.
SIGH

if that's the people walk over a sea video (has been removed): it's a hoax. i watched a 15 minute viral marketing video about it on a show a few days ago. they put a wood plank under the water.
then again you could always calculate it and see that a man won't be fast enough to make it.

Well, consider this:  A man of average weight can water ski barefoot at 60 mph.  A little less than that and he will sink.  So, for his weight and the surface area of his feet, the magic number of about 60 mph seems to work.

Of course, that is for planning, running is probably another set of circumstance entirely.
