Listen,
s = ut + 1/2 at^2
Now, the the stone is dropped from rest, u =0
Let the distance covered in last second be x
Therefore
19.6 - x = 0*t + 1/2 *10 1^2
=19.6 - x = 5
Therefore, x = 14.6
s = ut + 1/2 at^2
Now, the the stone is dropped from rest, u =0
Let the distance covered in last second be x
Therefore
19.6 - x = 0*t + 1/2 *10 1^2
=19.6 - x = 5
Therefore, x = 14.6
