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.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
