Q. Speed of two identical cars $u$ and $4u$ at a specific instant. The ratio of the respective distances in which the two cars are stopped from that instant is
A) $1:1$
B) $1:4$
C) $1:8$
D) $1:16$
Explanation
(d) $S \propto u^{2} \Rightarrow \frac{S_{1}}{S_{2}} = \left( \frac{1}{4} \right)^{2} = \frac{1}{16}$
