The building with the highest occupiable floor is currently the Sears Tower in Chicago. The top floor of the Sears Tower is 110 stories (436 m) above street level, and the roof of the tower is 442 m above the street. Assume a golf ball is thrown downward from the roof of the Sears Tower. Neglecting air resistance, the golf ball accelerates at 9.8 m/s2 and lands on the pavement after 9.2 s.
