Question 772909: The time in seconds that it takes for an object to fall from rest is given by t=1/4 sqrt(s), in which s is the distance fallen (in feet). Find the time required for an object to fall from the ground from a building that is 800 feet high. Round your answer to the nearest hundredth of a second.

------
time = (1/4)sqrt(800)
= (1/4)sqrt(400*2)
= (1/4)*20*sqrt(2)
= 5*sqrt(2) seconds.
