An early major objection to the idea that the earth rotates on its axis was that it would have to turn so fast that people would be thrown off into space. Show the error in this logic by

calculating:

a. the speed of a 100 kg person standing at the equator. (The radius of the earth is

about 6400 km).

b. the net force necessary to keep the person in this motion.

c. how the normal force acting on the person compares to their weight.

d. From your answers to these questions, explain why people do not fly off into

space. What would happen to the size of the normal force if the earth spun faster?
