To determine the required duration of the fall of the body, we will use the formula (the fall will be considered free): S = h = a * t ^ 2/2 = g * t ^ 2/2, whence we express: t = √ (2 * h / g) …
Variables and constants: h – fall height (h = 19.6 m); g – acceleration due to gravity (g ≈ 9.8 m / s2).
Calculation: t = √ (2 * h / g) = √ (2 * 19.6 / 9.8) = 2 s.
Answer: The fall will last 2 seconds.
