Someone tried to calulate the average speed of the fall of the building using 15 seconds as collapse time. This is the way he formulated this:
It can't be this simple, can it?

Ah, yes. Even with my severely limited knowledge of Physics I knew it would be very complex to calulate this in any precise way.
What I was hoping for was something like "Yes, resistance of water is much greater than air, and, although it is difficult to calculate precisely, it is obvious that...
The question has to do with the collapse of the south tower of the WTCs on 911.
According to the official version, the 911 Commission Report, the building collapsed in 10 seconds. Utilizing the formula above we can determine that an object falling from the top of the tower to the ground would...
Thank you very much for your answer. I forgot to explain that I am as far from a physicist as can be and that formulas like the one you gave here is way beyond me.
Let me put my question a little bit differently:
We have a bowling ball falling 1000 feet through a vacuum, through air and...
Hmm, damn - I was hoping for a simple answer to my questions.
Thanks for the replies, though.
Can't one say anything in general about the resistance of air contra vacuum contra water. I am thinking of something like: "the resistance of water on a bowlingball is tenfold the resistance of air...
Hey folks, new guy here!
I have a couple of, what I believe to be, pretty elementary physics questions. I hope you can help me adjust my formulas and help me figure this out!
I have this formula for calculating how long it takes an object to fall a certain distance:
Time(squared) = (2 x...
