Early skeptics of the idea of a rotating Earth said that thefast spin of Earth would throw people at the equator intospace. The radius of Earth is about 6.38 * 10^3 km. Show why this objection is wrong by calculating...
a. the speed of a 97-kg person at the equator
b. the force needed to accelerate the person in thecircle
c. the weight of the person
d. the normal force of Earth on the person, that is, theperson's apparent weight.
