Early skeptics of the idea of a rotating Earth said that the fast spin of Earth would throw people at the equator into space. The radius of Earth is about 6.38 x 103 km. Show why this objection is wrong by calculating

1. The weight of the person.

2. The speed of a 97-kg person at the equator.

3. The force needed to accelerate the person in the circle.

4. The normal force of Earth on the person, that is, the person’s apparent weight.
