I think this would be a problem of momentum. p=mv so if the momentum of the bullet is 20 (.01x200=20) then the recoil velocity should equal 10 m/sec (2x10=20). Good old Newtons 3rd Law.

Since momentum is conserved in this system, the initial momentum of the rifle and bullet is equal to the final momentum of the rifle. You can find the recoil velocity of the rifle by setting up the equation: (2 kg) * V = (0.01 kg * 200 m/s). Solve for V to find the recoil velocity of the rifle.

What is recoil of a gun?
Recoil is the backward force exerted on a gun when a bullet is fired. This force is a result of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. Recoil can affect accuracy and may cause discomfort or injury to the shooter if not properly managed.
How does a rifle demonstrate Newton's third law of motion?
When a rifle is fired, the bullet is propelled forward due to the force of the expanding gases pushing against it inside the barrel. Simultaneously, the rifle, in accordance with Newton's third law, experiences an equal and opposite force pushing backward, which is commonly known as recoil. This demonstrates the action-reaction principle of Newton's third law of motion.
When a 3.8 kg rifle fires a 13 gram bullet it experiences a recoil velocity of 2.4ms-1Calculate the velocity of the bullet?
Using the principle of conservation of momentum, we can set the initial momentum of the system to be equal to the final momentum of the system. The initial momentum is 0 (since the rifle and bullet are at rest initially), and the final momentum is the combined momentum of the rifle and bullet after firing. We can calculate the velocity of the bullet by dividing the momentum of the rifle by the mass of the bullet. Final momentum = Mass of rifle * Velocity of the rifle + Mass of bullet * Velocity of bullet 0 = 3.8 kg * 2.4 m/s + 0.013 kg * Velocity of bullet Velocity of bullet = - (3.8 * 2.4) / 0.013 ≈ -738.46 m/s, where the negative sign indicates opposite direction to the rifle.
Why does the gun recoils and puch the person back when fired?
When a gun is fired a bullet (or cartridge) with a small mass but a very high velocity is ejected. The recoil of the gun is a reaction to this force and is sufficient to push back the person who fired the weapon.
When bullet penetrates into the target what happens?
There is a Reaction, called recall or kick. That should read "recoil."
How can calculate recoil velocity of gun?
The recoil velocity of a gun can be calculated using the principle of conservation of momentum. The formula to calculate the recoil velocity is: Recoil velocity = (mass of bullet * velocity of bullet) / mass of gun. This formula takes into account the mass of the bullet, the velocity of the bullet, and the mass of the gun.
What is the Difference between muzzle velocity and recoil velocity?
Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.
A rifle is fired and you are able to measure both the muzzle velocity of the bullet as well as the recoil velocity of rifle how do you explain the fact that the forward velocity of the bullet is great?
The forward velocity of the bullet is greater than the recoil velocity of the rifle because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When the bullet is fired forward with high velocity, the rifle experiences a recoil in the opposite direction but with lower velocity due to the mass difference between the bullet and the rifle.
Which is greater the momentum of a bullet fired from a rifle or the momentum of the rifle's recoil?
The momentum of the bullet fired from a rifle is greater than the momentum of the rifle's recoil. This is because the bullet has a higher velocity and mass compared to the rifle, resulting in a greater momentum.
What is the recoil velocity of the pistol when a bullet of mass 20g is fired with a velocity 150ms from a pistol of mass 2kg?
The recoil velocity of the pistol can be calculated using the law of conservation of momentum. The initial momentum is 0 (since the system is not moving initially), and the final momentum is the sum of the momenta of the bullet and the pistol together. Therefore, the recoil velocity of the pistol would be 1.5 m/s in the opposite direction to the bullet's velocity.
What is recoil of a gun?
Recoil is the backward force exerted on a gun when a bullet is fired. This force is a result of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. Recoil can affect accuracy and may cause discomfort or injury to the shooter if not properly managed.
How the velocity of recoil of a gun fire is 1'100 times the velocity of bullet if mass of a gun is 100 times of mass of bullet?
Newton said "For every action, there is an equal and opposite reaction." The action is pushing the bullet in one direction. Reaction is the gun being pushed in the other. The energy is speed times mass. The gun masses much more than the bullet, and so will move proportionately slower than the bullet. Which is a very good thing- or the recoil of the gun would kill the shooter.
Why does a gun not recoil just as fast as the speed of the bullet?
because the recoil is when the bullet forces the gun back and so the bullet creates the recoil and so it can't make it go just as fast
Which will give a lesser recoil on a pistol..an ammunition with a heavier bullet or a lighter bullet?
light
What is the term recoil o f the gun?
Bullet forward, gun back - as in when the gun is fired, the bullet goes forward, and the explosion pushes (recoil) the gun backwards.
Bullet with mass 60.0 g is fired with an initial velocity of 575 ms from a gun with mass 4.50 kg The speed of the recoil of the gun you?
The momentum of the bullet is equal in magnitude but opposite in direction to the momentum of the gun. Use conservation of momentum to find the speed of the gun recoil. Since momentum is conserved, the momentum of the gun and bullet before they are fired is equal to the combined momentum of both after they are fired.
What is the recoil of a 308?
assuming that you talking about a .308 Winchester or the 7.62 NATO round recoil is factor of pure physics the lighter the weapon the greater the free recoil (kick).the heavier the bullet the greater the kick. the higher the velocity the more kick.there are many factors involved in calculating the recoil of any firearm.what does the gun weigh ?what is the barrel length? what is the bullet weight? is the gun a bolt action or auto-matic ? is it gas or recoil operated ? does it have a recoil reducer of some type? how effective is this recoil reducer? knowing the interior ballistics of a cartridge is only the beginning of calculating the recoil and barrel flip of any firearm. in my observation over many years most .308 guns have recoil effect of between 7-15 foot pounds of free recoil energy.
