Free Fallin' Again
An emailer named Nick McKenzie sent in this analysis. Because Blogger will not take superscripts, I have indicated them with a ^ symbol, so when you see s^2, that means s squared:
I am Canadian so I know the mesurements and my equations in metric, not imperial.
Acceleration due to gravity is 9.8m/s^2.
The WTC stood 415m tall (south tower, the one mentioned in the video) and had 110 floors. Each floor was therby around 3.772m tall. (415/110) Since the aircraft hit around the 80th floor, we will measure the speed from there. the 80th floor was around 301.76m high (3.772 x 80).
So- total displacement= 301.76m
time=around 10 seconds. (time suggested in loose change)
d=iniv(t0 +1/2a (t^2)
Therefore the tower fell with an acceleration of 6.0352m/s^2, around 3.8m/s^2 slower than freefall speed.
Lets find time instead.Given list same as above except lets put 9.8 for acceleration and solve for t.
Therefore, if the WTCs had fallen at freefall speeds they would have fell in 7.84 seconds, almost 2 seconds off from Avery's doctored tape that attempts to prove the towers fell at freefall speeds.
Let me point out here that I am still uncertain how anybody can look at the WTC videos and pinpoint the exact time the towers stopped falling. As we have discussed, the heavy parts the debris field falls faster than the towers themselves. In addition, much of the dust and stuff falls slower than the towers, resulting in the buildings themselves being obscured.
