Give an example in support of law of conservation of momentum .

Explanation

**Step-by-Step Solution:**

1. **Understanding Momentum**:
- Momentum (p) is defined as the product of mass (m) and velocity (v), given by the formula:
\[ p = m \times v \]
- The law of conservation of momentum states that in a closed system, the total momentum before an event must equal the total momentum after the event.

2. **Setting Up the Example**:
