A marksman wishes to hit a target just in the same level as the line of sight. How high from the target he should aim, if the distance of the target is 1600 m and the muzzle velocity of the gun is `800 ms^(-1)` ? Take `g = 9.8 ms^(-2)`.

A particle is fired horizontally with a velocity of 100 ms^(-1) for the top of a hill 400 m high. Find (i) the time taken to reach the ground (ii) thedistance of the target from the hill and (iii) the velocity with which the projectile hits the ground. Take g= 10 ms^(-2) .

A bomb is flying horizontally at a heitht of 2000 m with a speed of 200 ms^(-1) . When a bomb is relesed from it . Find (i) the time taken by bomb to resch the ground(ii) the velocity with which the bomb hits the target and the distance of the target and the distance of the target from where the bomb is dropped. Take g=10 m//s^(-2) .

a 100kg gun fires a ball of 1kg horizontally from a cliff of height 500m. If falls on the ground at a distance of 400m from the bottom of the cliff. The recoil velocity of the gun is (Take g: 10ms^(-2)

A bulley with muzzle velocity 100 m s^-1 is to be shot at a target 30 m away in the same horizontal line. How high above the target must the rifle be aimed so that the bullet will hit the target ? .

A jet aeroplane is flying at a constant height of 2 km with a speed 360 kmh^(-1) above the ground towards a target and releases a bomb. After how much time it will hit the target and what will be the horizontal distance of the aeroplane from the target so that the bomb should hit the target ? (Take g = 10 ms^(-2))

A machine gun is mounted on the top of a tower of height h . At what angle should the gun be inclined to cover a maximum range of firing on the ground below ? The muzzle speed of bullet is 150 ms^-1 . Take g = 10 ms^-2 .

A ballon is assconding at the rate of 14 ms ^(-1) at a height of 98 m above the ground when velocity does it reach the ground ? Take g 9.8ms ^(-2) .

From the top of a hill 480 m high , a projectile is fired horizontally with a speed of 96 m//s . Calculate (i) the time taken by projectile to reach the ground . (ii) the distance of the target from the hill . (iii) the velocity with which the projectile hits the ground . Take g=10ms^(-2)
