Acceleration from gravity is 9.8 m/s^2. Integrate that to get 9.8t+0 for the velocity function (initially 0). Integrate that to get 9.8t^2+0t+0 for the position function (initially 0). Plug in 9.2 seconds to find its position that many seconds after dropping. The position is how far it is from 0, or its starting point, the top of the building.
I think.
