Which energy transfer takes place?
From the kinetic store of the car to the gravitational store of the car
From the chemical store of the fuel to the kinetic store of the car
From the kinetic store of the car to the thermal store of the brakes
From the thermal store of the brakes to the kinetic store of the car
