Explanation:
Here, Initial velocity u=0 <br> final velocity v=? (to be calculated ) <br> Acceleration due to gravity
(Stone comes down ) <br> And Height h=19.6 m <br> Now ,we know that for a freely falling body : <br>
<br> So ,
<br>
<br>
<br> v=19.6 m/s <br> Thus the velocity of stone just before hitting the ground will be 19.6 metres per second .
Because the stone came at rest
