Answer:
given = height =5m
time = 0.2 sec
to find = speed of third drop when 1st drop hits the ground.
solution,
s= 1/2 gt²
5 = 1/2 X 10 X t²
T = 1 sec
the time interval is 1/2 sc
it means every half of the second the drop will released.
we have to find time when 3rd drop is released,
s = 1/2gt² X t²
s = 1/2 X 10 X 1/ 4
s = 5/4
s = 1.25 m
