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
