When a bullet is fired from a gun What is the total momentum of the gun and the bullet and explain why?
Answer: When a bullet is fired from a gun ,total momentum of bullet is zero since nothing is moving.
When a bullet is fired from a gun What is the total momentum of the gun and bullet a finite value B Cannot say C zero D None?
The gun and the bullet are both at rest, so the momenta (mv) of the gun and the bullet are both zero. So, the total momentum of the system before the bullet is fired is zero.
When a bullet is fired from a rifle then the total momentum of the bullet and rifle is?
zero
When a bullet is fired from a gun, total momentum before is zero since nothing is moving. After firing the bullet there is a momentum in the forward direction.
What is the total momentum of a bullet and a gun before firing write an expression for recoil velocity of gun?
The sum of momentum before firing bullet is zero. mu1+Mu2=0If v1 and v2 are the final velcoities of bullet and gun receptively after firing. Total momentum before recoil = Total momentum after recoil.
What is the total movement of a bullet and a gun before firing?
The total momentum of the bullet and the gun before the firing is zero because both are at rest.
When a bullet is fired from a gun at rest Net finite momentum of bullet plus gun is zero?
Answer: Assertion is true because momentum of system ( gun \(+\) bullet ) as a whole is conserved because the net external force on the system is zero. Reason is false as internal forces can not cause a change in the linear momentum of the system.
When a bullet is fired from a rifle?
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
What do you mean by recoil velocity of a gun?
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.
When a bullet is fired from a gun at rest?
Assertion (A): When a bullet is fired from a gun at a rest, net finite momentum of bullet plus gun is zero. Reason(R): Internal forces can cause a change in linear momentum of the system.
