Velocity of recoil of gun is much smaller than the velocity of bullet. This is beaacuse

A

gun is much heavier than the bullet

B

gun is held tightly

C

either (a) and (b)

D

neither (a) or (b).

Text Solution

Verified by Experts

The correct Answer is:
A
As `m_(1)v_(1)+m_(2)v_(2)=0 :. v_(2)= - (m_(1)v_(1))/(m_(2))`
As `m_(2) gt gt m_(1)`, therefore `(-)v_(2)lt lt v_(1)`

Recoil velocity of gun is much smaller than the velocity of bullet. Why?

Recoil velocity of gun is

Statement I : When a gun is fired it recoils ,i.e., it pushes back , with much less velocity than the velocity of the bullet . Statement II : Velocity of the recoiling gun is less because the gun is much heavier than the bullet .

A circular wooden hoop of mass m and radius R rests fiat on a frictionless surface. A bullet, also of mass m and moving with a velocity v , strikes the hoop and gets embedded in it. The thickness of the hoop is much smaller than R . Find the angular velocity with which the system rotates in after the bullet strikes the hoop.

A bullet of mass m is fired from a gun of mass M. The recoiling gun compresses a spring of force constant k by a distance d. Then the velocity of the bullet is

A gun of mass kg 10 fires 4 bullets per second. The mass of each bullet is 20 g and the velocity of the bullet when it leaves the gun is 300ms^(-1) . The force required to hold the gun while firing is

A bullet of mass m is being fired from a stationary gun of mass M. If the velocity of the bullet is v, the velocity of the gun is-

A bullet leaves the rifle of mass one kg and rifle recoils thereby with velocity 30 cm/s. If the mass of the bullet is 3 g, the velocity of the bullet is

A machine gun fires 240 bullets per minute. If the mass of each bullet is 10 g and the velocity of the bullets is 600 ms^(-1) , then find power (in kW) of the gun.
