**drwls**, Monday, October 12, 2009 at 6:41amLet H be the distance from the top of the building to the top of the window.

Let T be the time for the stone to reach that point. g = 9.91 m/s^2

Here is what you knmow:

H = (1/2) g T^2

H + 2.25 = (1/2) g (T + 0.134)^2

Combining the two equations, you can eliminate H

2.25 = (1/2) g [0.268 T + 0.018]

Solve that for T; then compute H with one of the original equations.
