44. Galelio Galilei developed a formula for freely falling objects described by
where d is the distance in feet that an object falls in t seconds.

45. If the Leaning Tower is abut 180 feet tall use Galileo’s formula to determine how long it would take an object dropped form the tower to fall to the ground.
