A stone fell from the roof of the building what is the height of the building if the stone fell for 1.5 seconds.

To find the height of the buildings in question, we apply the formula (we take into account that the stone fell from the roof of the building without an initial speed): S = h = a * t ^ 2/2 = g * t ^ 2/2.

Constants and variables: g – gravitational acceleration (g ≈ 10 m / s2); t is the time of the stone falling (t = 1.5 s).

Calculation: h = g * t ^ 2/2 = 10 * 1.5 ^ 2/2 = 11.25 m.

Answer: The height of the building in question is 11.25 m.
