1. С какой высоты был сброшен камень, если он упал на землю через 3 с?

А. 45 м.

Б. 90 м.

В. 60 м.

Решение. №1 (с. 35)

1. Дано:

Время падения камня, $t = 3$ с

Начальная скорость, $v_0 = 0$ м/с (поскольку камень был сброшен)

Ускорение свободного падения, $g \approx 10$ м/с²

Найти:

Высоту, $\text{h}$

Решение:

Движение камня является свободным падением, то есть равноускоренным движением. Высоту, с которой падает тело при свободном падении, можно определить по формуле пути для равноускоренного движения:

$h = v_0t + \frac{gt^2}{2}$

Так как камень был сброшен, а не брошен, его начальная скорость $v_0$ равна нулю. Поэтому формула упрощается до вида:

$h = \frac{gt^2}{2}$

Теперь подставим в формулу известные значения. В школьных задачах для упрощения расчетов ускорение свободного падения $\text{g}$ часто принимают равным 10 м/с².

$h = \frac{10 \text{ м/с}^2 \cdot (3 \text{ с})^2}{2} = \frac{10 \text{ м/с}^2 \cdot 9 \text{ с}^2}{2} = \frac{90 \text{ м}}{2} = 45 \text{ м}$

Полученное значение 45 м соответствует варианту ответа А.

Ответ: А. 45 м.
