Answer:
666.67 kg is the mass of a car.
Explanation:
Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s


666.67 kg is the mass of a car.
