per second, then it is not free fall. 9.2 seconds is the time it would take the roof to reach the sidewalk at free fall acceleration.
Did the roof EVER reach the sidewalk? I doubt it. How high was the debris pile? At the point the building ceased collapsing, it was some 40m shy of the sidewalk.
376m = (.05)*(t m/s/s)*(9.2*9.2)
That would be more like 8.9 m/s/s...NEAR free fall, would be more accurate.
