Solved: Because of Earths rotation about its axis, a point
Chapter 7, Problem 7.95(choose chapter or problem)
Because of Earths rotation about its axis, a point on the equator has a centripetal acceleration of 0.034 0 m/s2, whereas a point at the poles has no centripetal acceleration. (a) Show that, at the equator, the gravitational force on an object (the objects true weight) must exceed the objects apparent weight. (b) What are the apparent weights of a 75.0-kg person at the equator and at the poles? (Assume Earth is a uniform sphere and take g 9.800 m/s2.)
