A person is standing on the equator. What is the person's displacement (in kilometers) after 1 revolution of the planet? Facts: The Earth rotates around the axis of
rotation once every 23 hours and 56 minutes. The circumference (distance around something) is 40,075 kilometers.

Answers
The person has no displacement
Explanation:
The given parameters are
The location of the person = The equator
The distance covered in one revolution = Total distance around the body
The total distance around the Earth = The circumference of the Earth = 40.075 kilometres
The total distance moved by the person standing at the equator during the Earths complete revolution = 40,075 kilometres
The initial location of the person in relation to a fixed point in space outside Earth at the start of the revolution = x km
The final location of the person in relation to the fixed point in space outside Earth at the completion of the revolution = x km
The displacement = Change in position = Final location - Initial location
∴ The displacement = x km - x km = 0 km.
