Напишите пожалуйста тему и идею стихотворения "Вірш Іванові Франкові" М.Вороний.

Расстояние s (в м), которое пролетает тело при свободном падении, можно приближенно вычислить по формуле s=vt+5t^2, где v – начальная скорость (в м/с), t – время падения (в с). На какой высоте над землей окажется камень, упавший с высоты 140м, через 4 с после начала падения, если его начальная скорость равна 2м/с? Ответ дайте в метрах.
