More people end up in U.S. emergency rooms because of fall-related injuries than from any other cause. At what speed v would someone hit the ground who accidentally steps off the top rung of a 8.00 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 +y direction point vertically upward and the origin be on the ground. U = m/s

Transcribed Image Text:A small object begins a free-fall from a height of H = 83.0 m at fo = 0 s. After t = 2.55 s, a second small object is launched
vertically up from the ground with an initial velocity of vo = 40.4 m/s. At what height from the ground will the two objects
first meet?
