Question 2561
You are driving your passenger car at 50 km/h. If you double your speed, will the braking distance also double?
- No, it will increase by more than that.
- Yes.
Show answer and explanation
Correct answer: No, it will increase by more than that.
Braking distance increases with the square of speed. Going from 50 to 100 km/h approximately quadruples it under equivalent conditions; it does not double it.
