Answer
The car's kinetic energy is converted into heat in the road and the car tires.
Work Step by Step
When the car is sliding on the road, the force of kinetic friction from the contact between the road and the tires exerts a force on the car in the opposite direction from the car's motion. The friction force does negative work on the car which removes the kinetic energy from the car.
The car's kinetic energy is converted into heat in the road and the car tires.
