Two objects are dropped from rest straight down from two different heights at the same time. It takes object A four times the amount of time as object B to reach the ground. If the initial height for object A is ha and that of object B is hg, how do the two heights compare? O ha - ha O ha - 2hg O ha - 4hB O ha - ha/16 O ha - 16hg O ha - ha/4 O ha - ha/2
