alfie · Answer

6ft : 25% = x ft : 100%
600/25 = 24ft

ok--i'm trying to figure out out how to determine which is the base, rate and amount

Well, I guess you are trying to do a kinematic's exercise now.
Since we are talking of a ball launched vertically, you just have one dimension
24ft = your initial point
-9,81m/s^2 = acceleration
0 = your final point

You can find pretty much all you need now ;).. good luck

h= original height 
so 25%h=0.25h=6 feet rises
h=6/0.25=24 feet

anonymous · Answer

if its in feet g=32.2 ft/sec^2
