Suppose an airplane flew east along the equator from the PrimeMeridian to the International Dateline; that is, exactly half wayaround the world. What is its final displacement? Is it thedistance covered by its route of flight (12,450 miles) or thedistance measured straight through the center of the earth (7,920miles)? Suppose the trip took exactly one day. What would be thedisplacement as observed from the Sun?
Suppose the airplane flew at a steady 450 miles per hour, withrespect to the surface of the Earth. Discuss, in qualitative(non-mathematical) terms, what its velocity would be with respectto other frames of reference: the center of the Earth, the Moon,the Sun, and the center of the Galaxy.
