A bullet mass 10gm is fired from a gun of mass 1 kg . If the recoil velocity is 5 `m//s`, the velocity of the muzzle is

Explanation

To solve the problem, we will use the principle of conservation of momentum. Here are the steps to find the velocity of the muzzle (the bullet):

### Step-by-Step Solution:

1. **Identify the masses**:
- Mass of the bullet, \( m = 10 \, \text{g} = \frac{10}{1000} \, \text{kg} = 0.01 \, \text{kg} \)
- Mass of the gun, \( M = 1 \, \text{kg} \)
