Water drops are falling in regular intervals of time from top of a tower to height 9 m. If 4^(th) drop begins to fall when 1^(st) drop reaches the ground, find the positions of 2^(nd) & 3^(rd) drops from the top of the tower.

Water drops fall from the roof a building 20 m high at regular time intervals. If the first drop strikes the floor when the sixth drop begins to fall, the heights of the second and fourth drops from the ground at that instant are (g = 10 ms^(-2))

Drops of water fall at regular intervals from the roof of a building of height H = 5 m, the first drop strikes the ground at the same moment when the fifth drop detaches itself from the roof. Then ratio of distances as first drop reaches the ground are :

Drops of water fall at regular intervals from the roof of a building of height h=16m . The first drop striking the ground at the same moment as the fifth drop is ready to leave from the roof. Find the distance between the successive drops.

Water drops are falling from a tap at regular time intervals. When the fifth drop is near to fall from tap the first drop is at ground. If the tap is fixed at height H from ground then find out (i) the height of the second drop from ground (ii) distance between the second and third drop (iii) velocity of third drop

Water drops fall from a tap on to the floor 5.0 m below at regular intervals of time. The first drop strikes the floor when the fifth drops beings to fall. The height at which the third drop will be from ground at the instant when the first drop strikes the ground is (take g=10 m^(-2) )

A dics is rotating in a room. A boy standing near the rim of the disc of radius R finds the water droplet falling from the ceiling is always falling on his head. As one drop hits his head, other one starts from the ceiling. If height of the roof above his head is H , then angular velocity of the disc is

Water drops fall at regular intervals from a tap 5 m above the ground. The third drop is leaving the tap, the instant the first drop touches the ground. How far above the ground is the second drop at that instant. (g = 10 ms^-2)
