In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5190 kmkm away, and released. It found its way back to its nest 13.5 daysdays after release. If we place the origin in the nest and extend the +x+x-axis to the release point, what was the bird's average velocity for the return flight? Express your answer in meters per second. vav.−xvav.−x = ________________ m/s   What was the bird's average velocity for the whole episode, from leaving the nest to returning? Express your answer in meters per second. vav.vav. = __________________ m/s
