The formula S=16t^2 is used to approximate the distance S, in feet, that an object falls freely from rest in t seconds. The height of a building is 1250 feet. How long would it take for an object to fall from the top?

t^2 = S/16 = 1250/16 t = 25√(2) /4 ~ 8.839 secs

S = 16t² = 1250 , solve for t , t>0
