Karimen (provisional) test Speed & stopping distance
If speed doubles, braking distance roughly doubles.
The real test question (Japanese)
制動距離は、速度が2倍になるとおよそ2倍になる。
Show answer and explanation
Answer: ✕ False
Braking distance rises with the square of speed, so doubling the speed roughly quadruples it.
制動距離は速度の二乗に比例するので、速度が2倍ならおよそ4倍になります。
