Question

a free falling stone from height 10 metre when reaches the earth its final velocity would be ____ m/s​

Answer 1

Explanation:

10 is the answer of this question

Answer 2

S (height) = 10m
initial velocity (u) = 0 (assumed)
acceleration due to gravity (g) = 9.8 m/s^2

to find: final velocity (v)

from the formula of motion
v^2 = u^2 + 2aS
=0 + 2*9.8*10
= 196

and v = 14 m/s
