A separatist Droid Army bettlestation is damaged during an intense battle over Coruscant, and it begins to fall towards to planet with an acceleration of s' = -gR^2/s^2 where s is the bettlestation's distance from Coruscant's center and R is Coruscant's radious. g = 30ft/sec^2 , R = 4000 mi, and the initial hight above the planet is H = 400 mi. What is the bettlestation's impect speed.
