A person sitting on the top of a tall building is dropping balls at regular intervals of one second. Find the positions of the 3rd, 4th and 5th ball when the 6th ball is being dropped.

Two balls of equal size are dropped from the same height from the roof of a building . One ball has twice the mass of the other. When the balls the ground, how do the kinetic energies of the two balls compare ?

The balls are released from the top of a tower of height H at regular interval of time. When first ball reaches at the ground, the n^(th) ball is to be just released and ((n+1)/(2))^(th) ball is at same distance 'h' from top of the tower. The value of h is

A ball is dropped from the top of a building. The ball takes 0.50 s to fall past the 3m length of a window, which is some distance below the top of the building. (a) How fast was the ball going as it passed the top of the window? (b) How far is the top of the window from the point at which the ball was dropped? Assume acceleration g in free fall due to gravity to be 10 m//s^(2) downwards.

A ball is dropped from the top of a building. The ball takes 0.5s to fall the 3m length of a window some distance from the to of the building. If the speed of the ball at the top and at the bottom of the window are v_(T) and v_(T) respectively, then (g=9.8m//s^(2))

A ball is thrown upward from the top of a 25.0 m tall building. The ball's initial speed is 12.0 m/s. At the same instant, a person is running on the ground at a distance of 31.0 m from the building. What must be the average speed of the person if he is to catch the ball at the bottom of the building ?

Drops of water from the roof of a house 6 m high fall at regular intervals. The first drop reaches the ground at an instant of time when third drop leaves the roof. Find the height of the second drop at that instant
