Vedclass · Answer

(D) The distance travelled by a freely falling object is given by the equation $s = \frac{1}{2}gt^2$. Since $g$ is constant, the distance $s$ is directly proportional to the square of the reaction time $t$ $(s \propto t^2)$. Comparing the reaction times: $t_B (0.22 	ext{ s}) > t_E (0.21 	ext{ s}) > t_A (0.20 	ext{ s}) > t_D (0.19 	ext{ s}) > t_C (0.18 	ext{ s})$. Since $s \propto t^2$, the order of distances will be the same as the order of the squares of the reaction times. Therefore, the distance travelled will follow the order: $B > E > A > D > C$. Thus, option $D$ is correct.
