Answer 2

The kinetic energy of an object is given by:

`K= (1)/(2)mv^2`
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`
