From ground a balloon starts ascending at a constant speed of `25 m//s`. After 5 sec. a bullet is short vertically upwards from the ground. The minimum speed of bullet at which it is able to hit the balloon will be:

A balloon starts ascending from the ground at a constant speed of 25 m//s . After 5 s, a bullet is shot vertically upwards from the ground. (i) What should be the minimun speed of the bullet so that it may reach the balloon? (ii) The bullet is shot at twise the speed calculated in (i). Find the height at which it passes the balloon.

A ball is thrown vertically upward with a speed v from a height h above the ground . The time taken for the ball to hit the ground is

A balloon starts rising from ground with an acceleration of 1.25 m//sec^2 . A 8 seconds a stone is released from the balloon. The maximum height from the ground reached by stone will be.

A balloon starts rising from the ground with an acceleration of 1.25ms^-2 . After 8 seconds, a stone is released from the balloon. After releasing, the stone will:

A balloon starts rising from the ground with an acceleration of 1.25ms^-2 . After 8 seconds, a stone is released from the balloon. After releasing, the stone will:

A man in a balloon, rising vertically with an acceleration of 5 m//s^(2) , releases a ball 10 s after the balloon is let go from the ground. The greatest height above the ground reached by the ball is

A man in a balloon, rising vertically with an acceleration of 5 m//s^(2) , releases a ball 10 s after the balloon is let go from the ground. The greatest height above the ground reached by the ball is

A balloon starts rising from thee ground with an acceleration of 1.25 m//s^(2) . After 8 s, a stone is released from the balloon. The stone will (taking g = 10 ms^(-2) )
