Answer 1

Answer:

Mass of Bullet (m) = 50 grams.

Velocity of the Bullet after Firing (u) = 35m/s.

Mass of The Rifle (M) = 4 kg.

Let the recoil velocity of the Pistol be "v".

From Law of Conservation of momentum,

Initial Momentum = Final Momentum.

But Before Firing,

The whole system(Gun & Bullet) is at Rest.

Therefore, Initial momentum will be zero. Then the equation becomes,

Now,

Formulating the Values of Final Momentum.

M = Mass of Rifle.

m = Mass of Bullet.

u = Velocity of bullet.

v = Velocity of Rifle.

Substituting the values,

(Mass of bullet (m) is 50 grams = 50 × 10⁻³ Kg.)

Simplifying,

Approximately it Equals,

So, the Initial Recoil velocity of Rifle is 0.44 m/s
