Per NCERT Example 2.6, doubling the INITIAL VELOCITY of a vehicle increases its stopping distance by what factor?
A4 times (since stopping distance ∝ v₀²)
B2 times
C8 times
DNo change
Answer & Solution
Correct answer: A. 4 times (since stopping distance ∝ v₀²)
Per NCERT Example 2.6, d_s ∝ v₀². Doubling v₀ → 4× stopping distance. Important for road safety!
