Explanation:
The question in english is:
If the circumference of the Earth is 40075 km, At what speed does a person who is on the equator move?
We need to find the tangential speed
of a person that is on the Earth's equator (assuming the Earth moves following a uniform circular motion) and we onle have the value of the circumference
of the planet as data.
Since we assumed we are dealing with uniform circular motion, the tangential speed is expressed as:
Where:
On the other hand, the circumference
of a sphere (assuming the Earth has this shape) is given by the following equation:
Where
in this case.
Clearing
:
Substituting (4) in (1):
Finally:
