Final answer:
The momentum of a car with a mass of 2,000 kilograms and traveling at a velocity of 15 m/s is 30,000 kg·m/s.
Step-by-step explanation:
The momentum of an object is calculated using the formula momentum (p) = mass (m) × velocity (v). Given that the car has a mass of 2,000 kilograms and a velocity of 15 meters per second (m/s), we can calculate the momentum by multiplying these two values together.
Momentum = mass × velocity = 2,000 kg × 15 m/s = 30,000 kg·m/s. The unit of momentum is kilogram meters per second (kg·m/s), which represents how much motion the car has.
