More people end up in U.S. emergency rooms because of fall-related injuries than from any other cause. At what speed ? would someone hit the ground who accidentally steps off the top rung of a 6.00 ft tall stepladder? (That step is usually embossed with the phrase "Warning! Do not stand on this step.") Ignore the effects of air resistance. Let the +? direction point vertically upward and the origin be on the ground.
