Aperson driving a car applies the brakes. this produces friction, which stops the car. into which type of energy is the mechanical energy of the car converted? a. gravitational b. chemical c. light d. heat

D) Heat, because friction produces heat, not light, gravitational or chemical. hope this helps! : )

Heat energy.

Explanation:

We know that the mechanical energy of any object is equal to the sum of its kinetic energy and the potential energy. When a person applies brakes on the car such that it stops, the mechanical energy of the car is converted to the heat energy. It is due to the law of conservation of energy which states that the energy of the system remains conserved. It just gets converted from one form of energy to another.

Hence, the correct option is (d) "Heat energy".
