The answer to your question is 44.27 m/s


Answer:

The speed is around 4.33 meters per second.

Explanation:

In this case, the speed is defined with the following formula

[tex]v=\sqrt{2gh}[/tex]

Where [tex]g=9.81m/s^{2}[/tex] and [tex]h=100m[/tex].

Replacing these values, we have

[tex]v=\sqrt{2(9.81)(100)}=\sqrt{1962}\approx 44.3 m/s[/tex]

Therefore, the speed is around 4.33 meters per second.
