how fast (speed) do you free fall in meters per second after 1 second? ________ m/s\n10\n15\n5\n20

Explanation:

Step1: Recall free - fall formula

The formula for the velocity $v$ of an object in free - fall is $v = gt$, where $g$ is the acceleration due to gravity ($g\approx10\ m/s^{2}$) and $t$ is the time.

Step2: Substitute values

Given $t = 1\ s$ and $g\approx10\ m/s^{2}$, we substitute into the formula: $v=10\times1$.

Step3: Calculate velocity

$v = 10\ m/s$.

Answer:

10 m/s, A. 10
