Question

explain in terms of the conservation of momentum why the ratio of the masses of a bullet must be carefully considered​

Answer 1

Given:

We are asked to use our knowledge of momentum and momentum conservation to answer why the masses of a bullet must be carefully considered.

First, what is momentum?

The momentum of an object is defined as its velocity multiplied by its mass (
`\vec p=m \vec v`). Momentum is a conserved quantity; in other words it stays constant within a closed system. With that being said, what does this have to do with guns and bullets? We know that if momentum is conserved then,
`\vec p_(0) = \vec p_(f)` or
`m \vec v_(0) = m \vec v_(f)` (the momentum of the system before is equal to the momentum of the system after).

When we fire the gun, the momentum of the gun and the bullet are equal so we can say,
`m_(g) \vec v_(g) = m_(b) \vec v_(b)`, where
`\vec v_(g)` represents the recoil velocity. Now think about this equation for a second,
`m_(g) \vec v_(g) = m_(b) \vec v_(b)`. Now let me alter it slightly so that we can just look at the speed of the bullet.
`m_(g) \vec v_(g) = m_(b) \vec v_(b) \Longrightarrow \vec v_(b) = (m_(g) )/(m_(b)) \vec v_(g)`. We can change the bullets speed in two ways:

1) We increase the value of
`\vec v_(g)`, the guns recoil.

2) Increasing the ratio of the mass of the gun to the bullet.

Wouldn't it be logical to design the weapon so that we have minimal recoil? We wouldn't want to increase recoil as it is desirable for an accurate weapon. Thus, option 2 is more practical.
