In an experiment, a shearwater (a seabird) was taken from its nest, flown 4760 km away, and released. It found its way back to its nest 14.9 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

t = 14.9days * 24hr/day = 357.6h.

V = d / t = 4760 / 357.6 = 13.3km/h.

V = 13300m/h * (1/3600)h/s = 3.69m/s.

To calculate the average velocity for the return flight, we need to first determine the displacement and then divide it by the time taken.

Given:
Displacement (d) = 4760 km
Time (t) = 14.9 days

To convert the time from days to seconds, we'll use the conversion factor:
1 day = 24 hours * 60 minutes * 60 seconds = 86,400 seconds

So, the time (t) in seconds is:
t = 14.9 days * 86,400 seconds/day = 1,283,760 seconds

Now, we can calculate the average velocity (v):
v = d / t

Converting the displacement from km to meters:
d = 4760 km * 1000 m/km = 4,760,000 meters

Substituting the values into the formula:
v = 4,760,000 meters / 1,283,760 seconds = 3.703 m/s (approximately)

Therefore, the average velocity for the return flight of the shearwater was 3.703 m/s in the direction from the release point back to the nest.

To find the average velocity for the return flight, we need to calculate the displacement and divide it by the time taken.

In this case, the bird flew from the release point back to its nest. The distance between the release point and the nest is given as 4760 km. However, we need to convert this distance to meters since the unit of velocity is meters per second.

1 kilometer (km) is equal to 1000 meters (m). Therefore, 4760 km is equal to 4760 * 1000 = 4,760,000 meters.

Now, let's calculate the average velocity for the return flight.

Displacement = 4,760,000 meters (since the bird flew back to the nest)
Time = 14.9 days

However, we need to convert the time from days to seconds since the unit of velocity is meters per second.

1 day has 24 hours, and 1 hour has 60 minutes, and 1 minute has 60 seconds.
So, 14.9 days is equal to 14.9 * 24 * 60 * 60 = 1,286,560 seconds.

Now, we can calculate the average velocity:

Average velocity = Displacement / Time
= 4,760,000 meters / 1,286,560 seconds

Calculating this value:

Average velocity ≈ 3.698 m/s

The positive sign indicates the direction from the release point to the nest, which signifies that the bird was flying back towards its nest.
