The body falls freely to the ground from a height of 30 meters. What will be its speed when it hits the ground?

Free fall is the movement of a body near the surface of the Earth, which is affected by the force of gravity.

In order to find the free fall velocity of a body, you must use the following formula:

V = √2 x g x h, where

V is the speed of the body falling,
g – acceleration due to gravity, equal to 9.81 m / s²,
h is the height from which the body falls.

Then for h = 30

V = √2 x 9.81 x 30 = √588.6 = 24.3 m / s.

Answer: the speed of the body at the moment of impact on the Earth will be 24.3 m / s.
