The earth has a radius of 6.38 x 106 m and turns on its axis once every 23.9 h. (a) What is the tangential speed (in m/s) of a perso living in Ecuador, a country that lies on the equator? (b) At what latitude (i.e., the angle beta in the drawing) is the tangential speed one-third that of a person living in Ecuador?
