1. When a ruler falls vertically, 5 different persons catch it with different reaction times. ($g = 9.8\ m\,s^{-2}$) I. Person A has reaction time of 0.20 s. II. Person B has reaction time of 0.22 s. III. Person C has reaction time of 0.18 s. IV. Person D has reaction time of 0.19 s. V. Person E has reaction time of 0.21 s. What is the CORRECT order of the distance travelled by the ruler for each person?
