Two stones are releassed from the same height. One is released from rest and the other is thrown horizontally. Which stone will touch the ground first ?

A ball is dropped from a height of a building while another is thrown horizontally at the same instant. Do they touch ground simultaneously?

A stone is dropped from the top of a vertical pillar. When the stone has fallen through a height x, another stone is dropped from height y below the top of the pillar. Both the stones touch the ground at the same time . Prove that the height of the pillar should (x+y)^(2)/(4x) .

A balloon is rising upwards from rest with acceleration (g)/(8) . A stone is dropped from the balloon when it is at height H. Show that the time by which the stone will touch the ground is 2 sqrt((H)/(g)) .

Two pieces of stone are thrown vertically upwards at the same time. One reaches a height 35 m more than the other and touches the ground 2s later. What are the initial velocities of the stones ? [ g =10 "m.s"^(-2) ]

A balloon at rest on the ground is rising upward with acceleration (g)/(8) . A stone is dropped from the balloon when it is at height H. Show that the time taken by the stone to touch the ground is 1/2 sqrt((H)/(g)) .
