A crate with a mass of 120 kg glides through a space station with a speed of 2.5 m/s. An astronaut speeds it up by pushing on it from behind with a force of 210 N, continually pushing with this force through a distance of 6 m. The astronaut moves around to the front of the crate and slows the crate down by pushing backwards with a force of 180 N, backing up through a distance of 5 m. After these two maneuvers, what is the speed of the crate? fınal speed = i m/s
