The stone fell from a height of 45 M. Find the time of the fall of the stone.

The given tasks: h (the height from which the taken stone fell, the distance traveled) = 45 m; the fall of the taken stone is considered free.

Reference values: according to the condition g (acceleration of gravity) = 10 m / s2.

The duration of the fall of the taken stone is expressed from the formula: H = S = g * t ^ 2/2, whence t = √ (2H / g).

Let’s make a calculation: t = √ (2 * 45/10) = 3 s.

Answer: The taken stone fell from a height of 45 meters for 3 seconds.
