In Finnish driving safety and emergency procedures, how does doubling vehicle speed affect kinetic energy and braking distance?
Answer and explanation
Correct answer: A. Kinetic energy and braking distance quadruple (fourfold increase)
- Step 1: Kinetic energy is proportional to speed squared (); doubling speed () produces times the energy, quadrupling the braking distance. Answer: Kinetic energy and braking distance quadruple (fourfold increase). Why not the others: Linear braking distance assumptions lead to catastrophic underestimation of stopping distances.
