Explanation:
The formula for free fall:
Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= 1 2 g t 2 \frac{1}{2}gt^2 21gt2. v²= 2gh.

Answer:
let,
initial velocity=u
final velocity =v
acceleration due to gravity=g
time =t
and
height=h
by third equation
v²=u² + 2as
here u is 0
so
v²=2gh
or
v=√2gh
