In Hungarian road traffic rules, how does stopping distance change when vehicle speed is doubled from 50 km/h to 100 km/h?
Answer and explanation
Correct answer: D. The braking distance quadruples (multiplies by four times) due to kinetic energy
- Step 1: Kinetic energy is proportional to the square of velocity (E = 1/2 m v²); doubling speed quadruples braking distance. Answer: The braking distance quadruples (multiplies by four times) due to kinetic energy. Why not the others: Doubling speed increases braking distance fourfold, not twofold.
