Question 10
H

Two students, X and Y, each do a ruler-drop test. The ruler falls further before student X catches it.

Which statement is correct?

[1]
A

X has the shorter reaction time, because X caught a faster-moving ruler

B

Both have the same reaction time, because the ruler has the same acceleration

C

Y has the longer reaction time, because Y caught the ruler nearer its end

D

X has the longer reaction time, because the ruler fell for a longer time
