Momentum (p) is calculated using the formula:
\[ p = m \cdot v \]
where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
For the car with a mass of 1,900 kg moving at a velocity of 20 m/s, the momentum is:
\[ p = 1,900 \, \text{kg} \cdot 20 \, \text{m/s} = 38,000 \, \text{kg.m/s} \]
Therefore, the correct response is **38,000 kg.m/s**.
\[ p = m \cdot v \]
where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
