Answer:
666.67 kg is the mass of a car.
Step-by-step 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.
![Momentum(P)=Mass(m)* Velocity(v)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/br1ctp570h8ukxpzfvenlaqxt2n56d866t.png)
Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s
![m=(P)/(v)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/queml43ydyzb08mq8a18ky72rj9tzyh52p.png)
![m=( 10,000.00 kgm/s)/(15.0 m/s)=666.67 kg](https://img.qammunity.org/2020/formulas/chemistry/middle-school/n2sw6xycemtufzp3tytecqt11jpw2j5gq3.png)
