In what way does doubling of the motorcycle speed affect the braking distance?
Explanation
Correct answer: It quadrouples the braking distance.
The braking distance is directly proportional to the square of the vehicle's speed, which results from the basic laws of physics. This means that doubling the speed results in a fourfold increase in kinetic energy, which the brakes must dissipate. As a result, the stopping distance also increases fourfold.
