Question

In an experiment, a shearwater (a seabird) was taken from its nest, flown 4235 km away, and released. It found its way back to its nest 14.6 days after it was released. If we place the origin at the nest and extend the +x axis to the release point, what was the bird's average velocity for the following?

(a) the return flight (Indicate the direction by the sign of the velocity.)
.........m/s

(b) the whole episode, from leaving the nest to returning (Indicate the direction by the sign of the velocity.)
.........m/s

Explanation / Answer

The 2nd question is a trick question (I think).

Total displacement/total time = average velocity

0/Tt = 0 m/s (Does not matter what the total time was.)

1st question

4,235,000 m / (60 s/min * 60 min/hr * 24 hr/day * 14.6 days) = 4,235,000 / 1,261,440 = 3.357 m/s
