In an experiment, a shearwater (a seabird) was taken from its nest, flown 5150 $\mathrm{km}$ away, and released. The bird found its way back to its nest 13.5 days after release. If we place the origin in the nest and extend the $+x$ -axis to the release point, what was the bird's average velocity in $\mathrm{m} / \mathrm{s}$ (a) for the return flight, and (b) for the whole episode, from leaving the nest to returning?

Newton's Laws of Motion are three physical laws that, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. These three laws have been expressed in several ways, over nearly three centuries, and can be summarised as follows: In his 1687 "Philosophiæ Naturalis Principia Mathematica" ("Mathematical Principles of Natural Philosophy"), Isaac Newton set out three laws of motion. The first law defines the force F, the second law defines the mass m, and the third law defines the acceleration a. The first law states that if the net force acting upon a body is zero, its velocity will not change; the second law states that the acceleration of a body is proportional to the net force acting upon it, and the third law states that for every action there is an equal and opposite reaction.

In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

so party is trying to find the average velocity for the return flight. This is going to equal Delta X divided by Delta T and for the return flight they're flying Ah, 5,150 kilometers. But they are returning, so they're essentially moving backwards back to their origin. So 5,150 kilometers or 5,150,000 meters, and this is going to be they make the trip and they make the return trip and 13 and 1/2 days and we know that there are 86,400 seconds per day and so we can say that the average velocity is negative 4.42 meters per second. Again, this philosophy is negative because this is the return trip and then for part B, there's asking us for the average velocity for the whole for the entire trip. So the total trip and however this is going to equal zero meters per second. This is because the auto X equals zero. So if there isn't any displacement and in this case because they're making a complete trip to to the destination and from the destination, they're ending up in the same exact place. Therefore, the average velocity is going to be zero because again, displacement is there. L've meters. That is the end of the solution. Thank you for watching.
