the earth, of course, is rotating about its own axis, carrying us along with it at high speed. at the same time, it is revolving around the sun, carrying us with it at an even higher speed using the data from the appendices of the textbook, calculate the following speeds: a. the speed at which a point on the earth's equator is moving due to the rotation of the earth. b. the speed at which we're moving due to the rotation of the earth at the latitude of tulsa, 2. oklahoma (36°12' north of the equator). the speed at which the earth is moving in its orbit around the sun. the speed at which we're moving due to the combined effects of rotation (of the earth) and revolution (of the earth about the sun) at high noon. need to know: is the rotation of the earth adding to or subtracting from the speed of revolution? what effect does the "ilt" of the earth's axis have on this motion? explain your reasoning completely. c. d.
