The formula for a falling body due to gravity is: t = (2H/g)1/2 The 1/2 means square root. We have three separate building here of differing heights "H". It's a simple matter to calculate the time t for the free fall. WTC 1 was 1,368' high. WTC 2 was 1,362' high. WTC 7 was 570' high. Free fall time would be: WTC 1: 9.22 seconds WTC 2: 9.20 seconds WTC 7: 6.0 seconds The recorded time of collapse was: WTC 1: 10 seconds WTC 2: 10 seconds WTC 7: 6.5 seconds In each case the buildings collapsed in just slightly more than their free fall times. TMS has the time of collapse correct for 1 and 2, but they miscalculated the free fall time as you can see by the above formula and result.
