The height of a building is 1256 ft. How long would it take an object to fall to the ground from the top? Use the formula s=16t^2, where s is the distance, in feet, traveled by an object falling freely from rest in t seconds.

(Simply your answer. Type an integer or a decimal. Round to the nearest tenth.)
