In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5220km away, and released. it found its way back to its nest a time 12.8days after release. a. if we place the origin in the nest and extend the +x-axis to the release point, what was the bird's average velocity for the return flight? v= . what was the bird's average velocity in m/s for the whole episode, from leaving the nest to returning? v=

-4.72005 m/s

0 m/s

Explanation:

Displacement = 5220 km

Time = 12.8 days

The average velocity is given by

The average  for the return flight is -4.72005 m/s

When the total displacement is divided by the total time of a journey then we get the average velocity.

Displacement is the minimum distance between the initial and final points of the journey.

Here, the displacement of the whole episode is 0 as the initial and final point is zero.

Hence, the average velocity for the whole episode is 0 m/s
