A rock is shot vertically upward from the edge of the top of a tall building.The rock reaches its maximum height above the top of the building 1.60 s after being shot. Then, after barely missing the edge of the building as it falls downward, the rock strikes the ground 6.00 s after it is launched. In SI units: (a) with what upward velocity is the rock shot, (b) what maximum height above the top of the building is reached by the rock, and (c) how tall is the building?

A person is standing on the roof of a tall building . She throws a ball vertically only from the top of the building in such a way that when the ball passes a window cleaner who is 2.0m from the top, it is falling at a speed of 7.0m/s . It takes another 2.9 s to reach the ground . How tall is the building?
