Question: A rock takes 2.3 s to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.2 m/s.

Part I: How long would it take to reach the round if it's thrown straight down with the same speed?

Please explain your answer. I know substitution is involved so be sure to give a detailed explanation on that as well.
