Momentum is calculated using the formula:
\[ \text{Momentum} = \text{mass} \times \text{velocity} \]
In this case, if the velocity of the car doubles, the momentum will also double, assuming the mass remains constant.
Given that the original momentum is 20,000 kg • m/s, if the velocity doubles, the new momentum will be:
\[ 2 \times 20,000 \, \text{kg • m/s} = 40,000 \, \text{kg • m/s} \]
Therefore, the car’s momentum would be **40,000 kg • m/s**.
\[ \text{Momentum} = \text{mass} \times \text{velocity} \]
In this case, if the velocity of the car doubles, the momentum will also double, assuming the mass remains constant.
