A gun in mounted on a railroad car. Themass of the car with all of its components is 80 m mass of each shell to be fired is 5m. The muzzle velocity of the shells is 100m/s horizontally, what is the recoil speed of the car after seconds shot? Consider car to be at rest initially.

A gun is monted on a railroad car. The mass of the car, the gun, the shells and the operator is 50m where m is the mass of one shell. If the velocity of het shell with respect to the gun (in its state before firing) is 200 m/s, what is the recoil speed of the car after the second shot? Neglect friction.

The bullet of 5 g is shot from a gun of mass 5 kg. The muzzle velocity of the bullet is 500 m//s .The recoil velocity of the gun is

A shell of mass 0.020 kg is fired by a gun of mass 100 kg. If the speed of the shell is 80 m/s , the recoil speed of the gun would be

A gun of mass M at rest on a smooth surface fires a shell of mass m. the ratio of kinetic energy of the shell and gun after firing is :: (Assume that shell is fired horizontally).

A bullet of mass 10 g is fired from a gun of mass 1 kg with recoil velocity of gun 5 m/s. The muzzle velocity will be

A machine gun is mounted on a 2000kg car on a harizontal frictionless surface. At some instant the gun fires bullets of mass 10gm with a velocity of 500m/sec with respect to the car. The number of bullets fired per second is ten. The average thrust on the system is

A bullet mass 10gm is fired from a gun of mass 1 kg . If the recoil velocity is 5 m//s , the velocity of the muzzle is
