The momentum (p) of an object is calculated using the formula:
\[ p = m \times v \]
where:
- \( m \) is the mass of the object (in kg),
- \( v \) is the velocity of the object (in m/s).
For the car with a mass of 1,900 kg moving at a velocity of 20 m/s:
\[ p = 1,900 \, \text{kg} \times 20 \, \text{m/s} \]
Calculating this:
\[ p = 38,000 \, \text{kg.m/s} \]
So the correct answer is:
**38,000 kg.m/s**
\[ p = m \times v \]
where:
- \( m \) is the mass of the object (in kg),
- \( v \) is the velocity of the object (in m/s).
For the car with a mass of 1,900 kg moving at a velocity of 20 m/s:
\[ p = 1,900 \, \text{kg} \times 20 \, \text{m/s} \]
Calculating this:
\[ p = 38,000 \, \text{kg.m/s} \]
So the correct answer is:
**38,000 kg.m/s**
