172-Foot High Dive

actualy its 52km/h.. and 32.2 mp/h and he takes 3.2 to get to the water

is correct, ignoring effects of air resistance. But that means he'll be travelling at approximately 31 metres per second at impact, which is 113 km per hour, which is 70 miles per hour.

Don't know where you got 52km/h from - except that 172 feet is 52 metres - the height of the board.

that was not a straight fall. He jumped at least a foot up before falling !

i pretty much doubt it's an olympic sport.

you may get injured or even die... if you don't dive right you going to be in a world of pain

you can dive from any heigt, and still not go under 4 meters below surfise because the density of the water grows alot for every meter.

my english=not good

The density does not increase. The pressure increases....BuYAHH

you're right, more or less. Water is almost incompressible - but it is a tiny bit compressible, therefore the density will be a tiny bit higher. It's irrelevant for the purpose of this video, but in deep bodies of water the deep water is usually considerably colder and therefore relatively more dense than surface waters.

Do you agree?

But all matter is compressible to infinite density under enough pressure. Though it also does not apply in this case.

He jumped in feet first. No biggie. And one thing for sure, his nose wasn't getting sunburnt.

that you can jump from that high right asshole...

but how long would YOU need to get ready to possibly jump to your death?

The line between bravery and utter senselessness is frog hair thin.

but the climb up the ladder must be exhausting too. That's a high way up.

dis guy is cryzy i think, cuz he might hit d buttom of d pool from that height. hope he made it through that 1

are making it seem as if it is that easy. First off, wind resistance, although not negligible will not affect his velocity that much from such a distance. And as he is traveling 9.8ms-1, you cannot simply multiply to get the answer. He is accelerating all the way down. A car traveling at 100 mph will from point a to point b a hundred miles away take 60 minutes. A car at rest increasing in acceleration til it reaches 100mph will take more time to get to point b. Kinematics is more complicated than a times b equals c
