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.

K.E=(1mv^2)/(2)

m= mass of object = 1500 kg

v= velocity of object = 4 m/s

Putting in the values in the equation:

K.E=(1500kg* 4^2ms^(-1))/(2)

K.E=12000kgm^2s^(-2)=12000N
1kgm^2s^(-2)=1J

Thus Kinetic energy of the car is 12000 J.
