aaarrrggghhhh, feet and inches and stuff :(
anyway
if g = -32 ft/s^2
then I will have to admit that the distance fallen from a still start is
s = 16 t^2
(not r^2 by the way, falls straight down, not in a circle)
s = 16 (64) = 1024 answer B
which we did not need a calculator for because we have
s = 2^4 * 2^3 * 2^3
which is 2^10
which we all know is
1024
