Answer:- The Kinetic energy of the car is 12000 J.

Explanation:

Kinetic energy is the energy posessed by an object by virtue of its motion.

[tex]K.E=\frac{1mv^2}{2}[/tex]

m= mass of object = 1500 kg

v= velocity of object = 4 m/s

Putting in the values in the equation:

[tex]K.E=\frac{1500kg\times 4^2ms^{-1}}{2}[/tex]

[tex]K.E=12000kgm^2s^{-2}=12000N[/tex]      [tex]1kgm^2s^{-2}=1J[/tex]

Thus Kinetic energy of the car is 12000 J.
