You can reason that the time required for a ball to fall is related to the height from which it falls and to the acceleration due to gravity. Time is measured in seconds, height in meters, and gravitational acceleration. Using dimensional analysis, determine how the time to fall from height h compares to the time required to fall from height 2h.
A. It takes 1/2 as long
B. It takes 4 times as long
C. It takes 
times as long
D. It takes 2 times as long
E. It takes 
as long
F. It takes 1/4 as long
E. It takes
as long
