| May 18, 2021 | education
These tasks are: S (the path that the ball must travel after the start of free fall) = 19.6 m.
Reference values: g (acceleration of gravity of the ball in question) = 9.8 m / s2.
The duration of the fall of the ball under consideration is expressed from the formula: H = g * t ^ 2/2, whence t = √ (2 * H / g).
Calculation: t = √ (2 * 19.6 / 9.8) = 2 s.
Answer: The ball in question will be able to travel 19.6 m in 2 s.
