i know there is a certain height from where when you fall into the water you can no longer survive becuase its like hitting cement. how far is that?
i think it might be around 60 or 70 feet..
It is never like actually hitting cement, but can be pretty hard. This is to do with the speed you hit the water, which if you are jumping in relates to the height you have jumped from. Also relates to the angle you hit the water, if you hit it flat you will not penetrate as well and feel more of an impact. This happens because water is essentially incompressible - it is not very good at being squeezed so, if it cannot get out of the way fast enough, it is you who gets squeezed instead! Air on the other hand, is easier to move and is easily squeezed, so poses little resistance (unless you aretravelingg really fast).
