C)15 m.

Question

Quizplus · Accepted Answer

The vertical distance a stone falls in t seconds, when thrown horizontally (or simply dropped), can be calculated using the formula $d = \frac{1}{2}gt^2$, where $g$ is the acceleration due to gravity (approximately $9.8 \, \text{m/s}^2$). For $t = 1$ second, $d = \frac{1}{2} \times 9.8 \times 1^2 = 4.9 \, \text{m}$, which is approximately $5 \, \text{m}$.
