If the speed of the vehicle is doubled, how many times must the braking force be increased to stop the vehicle?

Two
Three
Four
Six

The correct answer is: Four

If the speed of the vehicle is doubled, the vehicle will have twice the kinetic energy. In order to bring the vehicle to a stop, the braking force must be equal to the kinetic energy. Therefore, the braking force must also be doubled. Since the question is asking for how many times the braking force must be increased, the answer is two times, which is option C. The other options are incorrect because they do not accurately describe the relationship between the speed and braking force. Option A suggests that the braking force only needs to be increased by two times, which is incorrect as the braking force must be equal to the kinetic energy of the vehicle. Options B, D and E suggest that the braking force needs to be increased by three, four, and six times respectively, which are also incorrect.
