Acrate with a mass of 120 kg glides through a space station with a speed of 5.0 m/s. an astronaut speeds it up by pushing on it from behind with a force of 220 n, continually pushing with this force through a distance of 4 m. the astronaut moves around to the front of the crate and slows the crate down by pushing backwards with a force of 190 n, backing up through a distance of 2 m. after these two maneuvers, what is the speed of the crate?
