As per your syllabus, doubling the INITIAL VELOCITY of a vehicle increases its stopping distance by what factor?

4 times (since stopping distance ∝ v₀²)
2 times
8 times
No change

Show answer and solution

Correct answer: A. 4 times (since stopping distance ∝ v₀²)

As per your syllabus, d_s ∝ v₀². Doubling v₀ → 4× stopping distance. Important for road safety!
