Final answer:
The braking distance of the blue car will be twice as great as the yellow car.
Step-by-step explanation:
The braking distance of the blue car will be twice as great as the yellow car (option C).
When two cars are traveling at the same speed, the braking distance is determined by the mass of the car. The blue car is twice as heavy as the yellow car, which means it has more inertia and requires more force to stop. Therefore, it will take a longer distance for the blue car to come to a complete stop compared to the yellow car.
