Stopping distance of a vehicle is proportional to which quantity?
AReciprocal of initial velocity
BSquare root of initial velocity
CSquare of initial velocity
DInitial velocity itself
Answer & Solution
Correct answer: C. Square of initial velocity
Setting v = 0 in v^2 = v0^2 + 2ax gives x = v0^2/2a, proportional to v0 squared.
