9/11 debunked, page-49

"I have done the maths grahod. I posted it a while ago. What more do you need to know anyway?

Free fall in a vacuum from 415m is 9.2 seconds. One of the towers fell in approx 15 seconds. Thus, the power of gravity only had some six seconds worth of energy to pulverise that building according to the law of conservation of energy. That is a lot of building in only six seconds to turn to dust."

Thats not the maths. Thats an assumption made from an equation that relates to different parameters.

Your stating in a vacuum an object would take 9.2 sec to fall 417 mtrs. Your stating, taking into consideration the atmosphere the sth tower fell through, 15 secs would equate to about the right freefall speed using the initial calculation based on an object free falling 417mtrs in a vacuum as a guide.

Your joking aren't you? The science is irrefutable we keep hearing and your ASSUMING that 15 secs is about right using another model?? Your not even a scientist or engineer in the first place. They don't work like that anyhow!!

Nice try! But you can't assume anything in science and state it as fact. Only way you can be certain that the sth tower fell 417 mtrs at freefall speeds in the atmosphere it fell through is using those SPECIFIC parameters.

So where is the maths that included those specific parameters that equated to 15 secs?

Still waiting ....
