Question

Quizplus · Accepted Answer

The maximum height (h) can be calculated using the formula $h = \frac{v^2}{2g}$, where $v$ is the initial velocity (10 m/s) and $g$ is the acceleration due to gravity (approximately 9.8 m/s$^2$). Plugging in the values, $h = \frac{10^2}{2 \times 9.8} = \frac{100}{19.6} = 5.1$ meters, which rounds to 5 meters, making option A correct.
