In Albanian driving safety, how does doubling travel speed (e.g., from 40 km/h to 80 km/h) affect kinetic energy and braking distance?
Answer and explanation
Correct answer: B. Kinetic energy and braking distance increase by four times (quadruple)
- Step 1: Under the Albanian Highway Code (Kodi Rrugor), Kinetic energy scales quadratically with velocity (); double speed quadruples stopping distance. Answer: Kinetic energy and braking distance increase by four times (quadruple). Why not the others: Kinetic energy and braking distance double does not represent the statutory Albanian safety standard.
