A person is standing on the South Pole. Their speed is zero (relative to the earth's axis) because they are not moving around due to the earths rotation (like standing in the middle of a merry-go round).

That person walks 100 meters North. What is their new speed due to earth's rotation?
Assume the person's circle that they are now moving is determined by the diameter of the daily circle at this location- which is 200 meters. (Note: a circle's circumference is given by diameter times pi; or 3.14 time a circle's diameter).

Give final answer with correct units and show how you calculated and arrived at this answer.
