Hey dear frnd....
your answer is here
height of wall is 20m.
let speed of baal is v when it hits the ground.
and let the time it's takes to fall through this height to be t.
initial speed of ball is zero.
then according to the equation of motion
v^2 = u^+2as
v^ = 0+ 2×10×20
v = 20 m/sec
and t = 20/10
t = 2 sec
Hope this help to you.
