7 feet. But since you dropped it on top of the Air Conditioner vent, it was suspended in air for a couple seconds before it hit the ground.

D = (1/2)*a*t^2 where a = acceleration & t = time a = 9.8 m/sec^2 t = 3.00 D = 44 m This is assuming no air resistance to slow the ball. Otherwise the building is actually shorter, but impossible to calculate without knowing the ball's detailed aerodynamics.
