If you dropped a led ball from the top of the former World Trade Center towers 1 or 2. How long would it take to hit the ground?? In a Vacume?? What would be the Terminal Velocity at sea level??
The official time the towers fell in the 911 commision report was 10 seconds. Is there a formula to figure out or estimate closely how much resistance the top floors above the impact point would have met on the way down verses resistance of air? Also note in the video the buildings fell at approx 10 seconds as well. How is this possible??
