A balloon is going up with a uniform speed 20 m/s. It was at a height of 100 m from ground, when a stone is dropped from its basket. Find the time taken by the stone to reach the groimd and the height of the balloon from the ground, when stone hits the ground. (Take `g = 10 m//s^(2)`)

A balloon is going vertically upwards with a velocity of 10 m//s . When it is 75 m above the ground, a stone is gently relesed from it. The time taken by the stone to reach the ground is (g=10 m//s^(2))

A balloon starts rising from the ground with an acceleration 2 ms^(-2) . After 5 second , a stone is released from the ballooon. Find the time taken by the stone to reach the ground after its release and total height attained by ballooon when stone reaches the ground. Take g==10 ms^(-2) .

A stone is dropped from a stationary hot air balloon in the air travels 14.7m in the last second before it hits the ground. Find the height of the balloon from the ground.

A balloon was moving upwards with a uniform velocity of 10 m/s. An object of finite mass is dropped from the balloon when it was at a height of 75 m from the ground level. The height of the balloon from the ground when object strikes the ground was around : (takes the value of gas 10 m//s^2)

A stone dropped from a building takes 4 s to reach the ground. The height of the building is

A stone is dropped from a rising balloon at a height of 76 m above the ground and reaches the ground in 6s. What was the velocity of the balloon when the stone was dropped?

A balloon starts rising from the ground with a constant acceleration of 1.25m//s^(2) . After 8 s, a stone is released from the balloon. Find the time taken by the stone to reach the ground. (Take g=10m//s^(2) )

A stone is dropped from the top of tower. When it has fallen by 5 m from the top, another stone is dropped from a point 25m below the top. If both stones reach the ground at the moment, then height of the tower from grounds is : (take g=10 m//s^(2) )

A balloon starts rising from ground from rest with an upward acceleration 2m//s^(2) . Just after 1 s, a stone is dropped from it. The time taken by stone to strike the ground is nearly

A stone is dropped from the roof of a building takes 4s to reach ground. The height of the building is
