Givens.

• Mass = 1,008 kg.

,

• Speed = 59 m/s.

The kinetic energy of the car depends directly on its mass and its squared speed.


K=(1)/(2)\cdot m\cdot v^2

Where m = 1,008 kg and v = 59 m/s.


\begin{gathered} K=(1)/(2)\cdot1,008\operatorname{kg}\cdot(59\cdot(m)/(s))^2 \\ K=504\operatorname{kg}\cdot3,481\cdot(m^2)/(s^2) \\ K=1,754,424J \end{gathered}

Therefore, the kinetic energy of the car is 1,754,424 Joules.
