Question

find the velocity of free falling body which depends on height and acceleration due to gravity.​

Answer 1

Answer:

$v = \sqrt{2gh}$

Explanation:

Suppose a body falling from a height 'h'

so it's initial velocity i.e. u = 0

Now the acceleration acting on a body is 'g'

As per newton law of motion

$v^{2}-u^{2} = 2gh$

here v is final velocity of body

so initial velocity is 0

then

$v = \sqrt{2gh}$
