Earth turns on its axis approximately once every 24 hours. The radius of Earth is 6.38 X 10^6 m.

a.) If some astronomical catastrophe suddenly brought Earth to a screeching halt (a physical impossibility as far as we know), with what speed would Earth's inhabitants who live at the equator go flying off Earth's surface?

b) Because Earth is solid, it must turn with the same frequency everywhere on its surface. Compare your linear speed at the equator to your linear speed while standing near one of the poles.
