**drwls**, Friday, December 28, 2012 at 2:54amCompute the times required to fall Y = 10 and Y = 12 m. Then subtract the 10 m time from the 12 m time. The will be the time spent crossing the window.

Y = (g/2) t^2

t(12 m) = sqrt (2Y/g) = 1.565 s

t(10 m) = sqrt (2*10/g) = 1.429 s

The difference is 0.136 s
