Not to sound rude or anything, but have you bothered reading through the rest of this thread? But I guess I'll go ahead and make a quick comment...
Now factor in the law of conservation of momentum, and the fact that each succesive floor along with it's trusses would offer resistance to the fall. And I don't recall the exact numberm but there's well over 100 floors. Do you really expect all that to happen in [roughly] 13 seconds?!? So you're telling me that an apple dropped from the top of the WTC with no horizontal initial velocity would land approximately the same time as the collapse? Heh, ok, whatever. BTW, there's something posted earlier on this thread, and pancacking should have taken atleast 59 seconds, unless you really thing 9-11 was such a special event that it defied the fundamental laws of newtonian physics. |
That 59 seconds is only if you start at the top and work all the way down each 100 floors. When you have a whole 30 some floor section of the building shift at once it takes a lot less time. 30 floors smashing onto the other 70 floors is quite a bit of weight. That's a ridiculous amount of force.
After falling for 13 seconds an apple would be traveling at over 400 ft./second, so yeah, it's entirely possible. Also, after only 12 seconds an apple or anything really will have fallen almost 2500 feet. Seeing has how the top of the top floor of the WTC was only 1365 or so feet high, it's not only possible it could happen within 9 seconds. Of course this is only based off the calculations I got from punching numbers myself. This is also only true if you believe Newton wasn't trying to hide the "truth".
