A boy aims a gun at a bird from a point, at a horizontal distance of `100m`. If the gun can impart a velocity of `500m//sec` to the bullet, at what height above the bird must he aim his gun in order to hit it?

A boy aims a gun at a bird from a point, at a horizontal distance of 100 m. If the gun can impart a velocity of 500 m/sec to the bullet, at what height above the bird must be aim his gun in order to hit it ?

A gun and a target are at the same horizontal level separated by a distance of 600 m. The bullet is fired from the gun with the velocity of 500 ms^-1 In order to hit the target , the gun should be aimed to a height h above the target. The value of h is (Acceleration due to gravity, g=10 ms^-2 )

A bullet of mass 5g is fired from a gun at a speed of 100m/s. If the barrel of the gun is of length 1m, then what will be the force caused by the gas, on the bullet?

A 10g bullet is short from a 5kg gun with a velocity of 400m//s . What is the speed of recoil of the gun?

A 10 gram bullet is shot from a 2 kg gun with a velocity of 400 m//s . What is the speed of recoil of the gun ?
