Question

how far do you fall from rest in free fall after 1 second?
0 m
5 m
10 m
20 m

Explanation:

Step1: Identify the formula

The formula for the distance $d$ fallen in free - fall from rest is $d = \frac{1}{2}gt^{2}$, where $g$ is the acceleration due to gravity ($g\approx10m/s^{2}$) and $t$ is the time.

Step2: Substitute values

Given $t = 1s$ and $g = 10m/s^{2}$, we substitute into the formula: $d=\frac{1}{2}\times10\times1^{2}$.

Step3: Calculate the result

$d=\frac{1}{2}\times10\times1 = 5m$.

Answer:

5 m
