A bicycle that travels twice as fast as another when braking to a stop will skid

Question

Quizplus · Accepted Answer

The distance skidded when braking to a stop is directly proportional to the square of the speed. Since the faster bike is traveling twice as fast as the slower bike, its speed is four times greater. Therefore, the distance skidded by the faster bike will be four times greater than the distance skidded by the slower bike, which is mathematically expressed as 2^2 = 4. Therefore, the faster bike skids four times as far as the slower bike.
