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 9.00 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.

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
