Question

Drops of water fall from the roof of a building 18m
high at regular intervals of time. When the first drop
reaches the ground, at the same instant fourth drop
begins to fall. What are the distances of the second
and third drops from the roof?
​

Answer 1

Answer:

Step-by-step explanation:

time taken to travel = 6/root 10

ratio = 2/root 10

time travel of second drop = 4/root10

time travel of third drop = 2/root10

distance of second drop from point of projection = 8 m

distance of third drop from point of projection = 2 m
