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))`.

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)) .

A balloon is rising upwards with an acceleration. A stone is dropped frome the balloon, is at a height of 50.4 m. The stone reaches the ground after 6s. What was the velocity of the balloon when the stone was dropped?

A stone is dropped from a height of 19.6m. What is the time taken by the stone to travel the last metre of the path?

A lift starts moving upwards from ground with a constant acceleration a cm. s^(-2) . After t s a piece of stone is dropped from it. Show that the stone touches the ground after (tsqrt(a))/(g) (sqrta+sqrt(a+g))s.

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 piece of stone is dropped from the top of a pillar. It travels the last h ft of the height in t s. Prove that the time of fall for the stone is ((t)/(2)+(h)/("gt")) s.

A body of mass 100g is dropped from the top of a tower 100m high. Find its kinetic energy (ii) just before it touches the ground.
