**drwls**, Friday, February 1, 2013 at 5:26amThe building height doesn't matter.

On its way down, as the thrown object passes the roof, its speed will again be 8 m/s, but DOWN. Since the object was thrown, the elapsed time is then (2*Vo)/g = 1.663 s. It will spend the remaining

t' = 4 - 1.663 = 2.406 seconds

falling to the balcony. Its velocity will then be 8.0 + gt' = 31.6 m/s
