u= 0
a = 9.8 m/sec square
s = 19.6 m
USING THIRD EQUATION OF MOTION
v square = u square + 2as
v square = 0 + 2 × 9.8 × 19.6
v square = 384.16
v = √384.16
v = 19.6 m/sec
ANSWER = 19.6 m/sec

Here's , Your Answer ...
=) Given , Height of tower = 19.6 m .
We know ,
Initial velocity of stone (u) = 0
Also , acceleration due to gravity (g) = 9.8 ms^-2
To find :- Final velocity of stone (v) = ?
Here ,
For free falling object =
Hence , the velocity of stone before touching the ground is 19.6 ms^-1 .
