A balloon is going upwards with velocity `12 m//sec` it releases a packet when it is at a height of 65 m from the ground. How much time the packet will take to reach the ground `(g=10 m//sec^(2))`

A balloon is going upwards with a velocity of 20 m It releases a packet when it is at a height of 160 m from the ground. The time taken by the packet to reach the ground is

A balloon is going vertically upward with a velocity of 15 ms^-1 . When it is at a height of 50 m above the ground a stone is gently dropped from it. The stone will reach the ground in time (take g = 10 ms^-2) :

A balloon is moving upwards with velocity 10m//s . It releases a stone which comes down to the ground in 11s . The height of the balloon from the ground at the moment when the stone was dropped is (g=10m//s^(2))

A balloon is moving upwards with velocity 10m//s . It releases a stone which comes down to the ground in 11s . The height of the balloon from the ground at the moment when the stone was dropped is (g=10m//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))
