Explanation:
Given
height from which ball is dropped 
and it rises to a height of 
A person caught the ball in mid-way i.e. at a height of
from pavement
time taken to reach the bottom is given by

where y=displacement
u=initial velocity
a=acceleration
t=time
here initial velocity is zero i.e.


Similarly to reach of height
time taken is 

The ball is caught in mid-way i.e. ball travel a distance of 
time taken is 
total time taken 



total time =3.429 s
