The Earth spins at 460 meters per second at the equator. The radius of the Earth is 6.37 x 106 m. A person who believes in a flat Earth says that if the Earth was round and spinning that fast we would all fly off. Imagine if you were standing inside a hollow earth. How much centripetal acceleration would you experience? How does this compare to the acceleration due to gravity we feel at the Earth’s surface? Does it explain why we don’t fly off the Earth due to the spin?
