Question

A body of mass 5 kg is moving with a velocity of 15 m/s. What is its momentum?

• A. \( 75 \, \text{kg} \cdot \text{m/s} \)
• B. \( 50 \, \text{kg} \cdot \text{m/s} \)
• C. \( 25 \, \text{kg} \cdot \text{m/s} \)
• D. \( 10 \, \text{kg} \cdot \text{m/s} \)

Hint:

Remember: Momentum is calculated using the formula \( p = m \times v \), where mass is in kg and velocity is in m/s.

Answer 1

The Correct Option is A

Step 1: Use the formula for momentum
Momentum \( p \) is given by the formula: \[ p = m v \] where:
- \( m \) is the mass of the body,
- \( v \) is the velocity of the body.
Step 2: Substitute the given values

We are given: - Mass \( m = 5 \, \text{kg} \),
- Velocity \( v = 15 \, \text{m/s} \).
Substitute these values into the formula: \[ p = 5 \times 15 = 75 \, \text{kg} \cdot \text{m/s} \] Answer: Therefore, the momentum of the body is \( 75 \, \text{kg} \cdot \text{m/s} \). So, the correct answer is option (1).
