$17)$Free fall: Two identical objects A and B fall from rest from different heights to the ground and feel no appreciable air resistance. If object B takes TWICE as long as object A to reach the ground, what is the ratio of the heights from which A and B fell? $17)$ A$)$hA$/$hB $=1/8$ B$)$hA$/$hB $=1/2$ C$)$hA$/$hB $=1/4$ D$)$hA$/$hB $=1/2$
