The most likely cause for the car to come to a stop in this scenario is that kinetic energy is transformed into thermal energy. This can be explained by the process of friction.
When the driver takes her foot off the gas pedal, the engine stops providing power to the car, which means no additional kinetic energy is being generated. However, the car still maintains its forward momentum due to its initial speed.
As the car moves forward, various forces start acting on it, including air resistance and friction between the tires and the road. These forces gradually slows down the car by converting its kinetic energy into other forms of energy.
One of the main factors responsible for the car coming to a stop is the friction between the tires and the road surface. As the car moves, the tires experience friction with the road, which creates heat. This heat energy is a form of thermal energy. At some point, the loss of kinetic energy due to friction and other forces will decrease the car's speed to zero, and it will come to a stop.
Therefore, the correct answer is A. Kinetic energy is transformed into thermal energy.
