Acrate with a mass of 60 kg glides through a space station with a speed of 2 m/s. an astronaut speeds it up by pushing on it from behind with a force of 180 n, continually pushing with this force through a distance of 7 m. the astronaut moves around to the front of the crate and slows the crate down by pushing backwards with a force of 160 n, backing up through a distance of 6 m. after these two maneuvers, what is the speed of the crate?

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?
