Question

An object of mass $ 0.5 \, \text{kg} $ is moving with a velocity of $ 10 \, \text{m/s} $. What is the momentum of the object?

• A. \( 5 \, \text{kg} \cdot \text{m/s} \)
• B. \( 10 \, \text{kg} \cdot \text{m/s} \)
• C. \( 50 \, \text{kg} \cdot \text{m/s} \)
• D. \( 0.5 \, \text{kg} \cdot \text{m/s} \)

Hint:

Momentum is a vector quantity, but in this case, we're only concerned with its magnitude.

Answer 1

The Correct Option is A

Step 1: Formula for momentum
Momentum \( p \) is given by the product of mass and velocity: \[ p = m v \]
Step 2: Substitute the given values
Given: - Mass \( m = 0.5 \, \text{kg} \) - Velocity \( v = 10 \, \text{m/s} \) \[ p = 0.5 \times 10 = 5 \, \text{kg} \cdot \text{m/s} \]
Answer:
Therefore, the momentum of the object is \( 5 \, \text{kg} \cdot \text{m/s} \). So, the correct answer is option (1).
