What is the magnitude of the momentum of the bullet after the rifle is fired?
After firing the bullet there is a momentum in the forward direction. The gun must therefore have the same magnitude of momentum but in the opposite direction so that they cancel each other out leaving the total momentum still equal to zero.
What is the recoil velocity of a rifle?
Recoil velocity is the backward velocity experienced by a shooter when one shoots a bullet. Due to the recoil velocity the shooter experiences a backward jerk. The recoil velocity is the result of conservation of linear momentum of the system.
What is the acceleration of a bullet from a rifle?
With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 105 m/s2. The acceleration of a bullet depends largely on the gun from which it is fired, along with the intent of the user.
What is the formula to find recoil velocity?
The initial velocity of the gun ×mass of the gun + Initial velocity of bullet × mass of bullet = Final velocity of the gun ×mass of the gun + Final velocity of the bullet × mass of the bullet.

What is the momentum of a bullet?
Public Domain Image, source: Christopher S. Baird. One of the most widely used handguns, the Beretta M9, has a typical bullet mass of 0.008 kilograms and a typical muzzle velocity of 400 meters per second. Multiply these two numbers together and you get a bullet momentum of about 3.2 kgm/s.
How do you calculate recoil velocity Class 9?
- Mass of the gun = M.
- Mass of the bullet = m.
- Velocity of the bullet = v.
- Recoil velocity of the gun = V.
- Total momentum of (gun + bullet) before firing = Total momentum of (gun+ bullet) after firing.
- 0 = MV + mv.
- MV = – mv.
- V = – mv/M.
What is the mass of a bullet?
A bullet can be no more than 0.02 to 0.4 kilograms….Mass of a Bullet.

How fast is a rifle bullet?
“The velocity (speed) of rifle bullets varies between 600 and 5000 feet (180 and 1500 meters) per second. Some bullets can hit targets as far away as 6000 yards (5000 meters).”
What is the recoil velocity of a gun of mass 8 kg?
0.5 m/s
Therefore, 0.5 m/s is the recoil velocity of the gun of mass 8 kg.
