Question

one day suresh father fired with his gun in the air . firstly the hold the gun tightly with his shoulder .what is the ​

Answer 1

To explain:

Why Suresh's father held the gun tightly with his soulder.

Solution:

• Whenever a person fires from a gun, the gun experiences recoil velocity in the opposite direction due to conservation of momentum.

• The mass of gun is much less as compared to a person (who is firing) , hence the recoil Velocity is large , which might lead to injury.

• So, Suresh's father held the gun tightly with his shoulder so as to increase the mass against which the gun will recoil.

• Due to effective increase in mass , the recoil Velocity decreases and reduces the chance of self-injury.

Let mass of bullet be m , mass of gun be M and Velocity of bullet be v;

$\therefore\sf{Recoil \:v = \dfrac{m \times v}{M}}$

$\boxed{\sf{=>Recoil \:v \propto \dfrac{1}{M}}}$

So, Suresh' father tried to increase the effective value of M by tightly holding the gun and hence reduced recoil Velocity.

Hope It Helps.

Answer 2

Explanation:

The given statement that when firing from a gun, it is important to hold it tightly.

This phenomena was explained by Newton in his thid law of motion that every action has an equal reaction but in opposite direction.

Now firing a bullet a a high speed requires alot of force, becasue of huge bullet acceleration. Therefore, when a bullet is fired, then an opposite force is applied towards the shoulders, so it is necessary to hold the gun, otherwise it might hurt the person firing the bullet
