Water drops fall at regular intervals from a tap which is 5 m above the ground. The third drop is leaving the tap at the instant the first drop touches the ground. How far above the ground is the second drop at that instant

A balloon is rising vertically up with a velocity of $29\;{\rm{m}}{{\rm{s}}^{ - 1}}.$ A stone is dropped from it and it reaches the ground in 10 s. The height of the balloon when the stone was dropped from it is $\left( {{\rm{g}} = 9.8{\rm{\;m}}{{\rm{s}}^{ - 2}}} \right)$

A balloon starts from rest and moves vertically upwards with an acceleration $\frac{g}{8}\,m/{s^2}$. A stone falls from the balloon after 8 s from the start. The time taken by the stone to reach the ground will be

A stone is thrown with an initial speed of 4.9 m/s from a bridge in vertically upward direction. It falls down in water after 2 sec. The height of the bridge is

A balloon is rising vertically up with a velocity of $29\;{\rm{m}}{{\rm{s}}^{ - 1}}.$ A stone is dropped from it and it reaches the ground in 10 s. The height of the balloon when the stone was dropped from it is $\left( {{\rm{g}} = 9.8{\rm{\;m}}{{\rm{s}}^{ - 2}}} \right)$

Velocity – time graph of a body thrown vertically up is

A ball dropped from the 9th story of a multi-storeyed building reaches the ground in 3s. In the first second of its free fall, it passes through n stories, where n is equal to (Take ${\rm{g}} = 10{\rm{m}}{{\rm{s}}^{ - 2}}$)

From the top of a tower, a particle is thrown vertically downwards with a velocity of $10{\rm{m}}{{\rm{s}}^{ - 1}}$. The ratio of the distances covered by it in the 3rd and 2nd seconds of its motion is (Given, ${\rm{g}} = 10{\rm{m}}{{\rm{s}}^{ - 2}}$)

A balloon rises from rest with a constant acceleration g/8. A stone is released from it when it has risen to height h. The time taken by the stone to reach the ground is

A balloon is at a height of 81 m and is ascending upwards with a velocity of 12 m/s . A body of 2kg weight is dropped from it. If $g = 10\;m/{s^2}$, the body will reach the surface of earth in

A stone falls freely from rest from a height h and it travels a distance $\frac{{9h}}{{25}}$ in the last second. The value of h is
