SUMMARY
The height of a building can be calculated using the formula y = 1/2at², where 'a' is the acceleration due to gravity (9.8 m/s²) and 't' is the time in seconds. In this case, a stone dropped from the top of the building takes 2.9 seconds to hit the ground. By substituting the values into the equation, the height is determined to be 41.2 meters. This calculation assumes the stone is dropped from rest, which is a standard assumption in physics problems of this nature.
