The kinetic energy of an object is given by:
![K= (1)/(2)mv^2](https://img.qammunity.org/2019/formulas/physics/middle-school/k8joxrbk5mr9tqpe8kskqja5ewh3w5h7vr.png)
where m is the mass of the object and v its velocity.
The car in this problem has a mass of m=600 kg and a velocity of v=10 m/s, therefore if we put these numbers into the equation, we find the kinetic energy of the car:
![K= (1)/(2)mv^2= (1)/(2)(600 kg)(10 m/s)^2=30000 J](https://img.qammunity.org/2019/formulas/physics/high-school/t7a78lg0x2j6f8bf01jqqmvbummiapnmgd.png)
