When an object is dropped from a building, its height above the ground is given by the formula \(h = y - gt^2\) where \(y\) is the height of the building in meters, \(g\) is a constant, and \(t\) is the time in seconds since the object was dropped. What is the height of an object dropped from a 100-meter tall building 2 seconds after being dropped?

(1) An object is 74 meters above the ground 2 seconds after being dropped from a building that is \(z\) meters tall.

(2) The height of an object dropped from a 150-meter tall building is 61.2 meters 3 seconds after being dropped.
