Mass of a moving body is doubled and velocity is halved . What will be the change in momentum ?

Explanation

To find the change in momentum when the mass of a moving body is doubled and its velocity is halved, we can follow these steps:

### Step-by-Step Solution:

1. **Define Initial Conditions**:
- Let the initial mass of the body be \( m \).
- Let the initial velocity of the body be \( v \).
