An aeroplane is flying in a hirizontal direction with a velocity of `360 kmh_-1` at a height of 490m. How far from a given target should it release a bomb so as to hit the target?

A mail bag is dropped into a post office, from an areoplane flying horizontally with a velocity 72hm/hr at height of 490m from the ground. How far must the plane be from the post office so that it may directly fall into the post office ?

A stone is thrown in a vertically upward direction with a velocity of 5 m s^1 . If the acceleration of the stone during its motion is 10m s^-2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?

A guy wire attached to a vertical pole of heigh 18 m is 24 m long and has a stake attached to the other end. How far from the base of tho pole should the stake be driven so that the wire will be taut?

A bomb is released from a horizontally flying bomber when it is directly above the * target. Will it hit the target?

A fighter plane flying horizontally at an altitude of .1.5 km with speed 720 km/h passes directly overhead an anti-aircraft gun. At what angle from the vertical should the gun be fired for the shell with muzzle speed 600 m s^-1 to hit the plane? At what minimum altitude should the pilot fly the plane to avoid being hit? (Take g = 10 m s^-2) .

A balloon ascending at the rate of 9.8 ms^(-1) is at a height of 39.2 m above the ground when a packet is dropped from the baloon. After how much time and with what velocity does it reach the ground? g= 9.8 ms^(-2) .
