As a satellite travels around Earth at an altitude of 22,320 mi, the magnitude of its linear velocity remains unchanged, but its direction changes continually, which means there is a change in velocity. Using a diagram based on Fig. 9.45, draw the difference in velocities (subtract the first velocity from the second) for the satellite as it travels 

(a) One-sixth, 

(b) One quarter of its orbit. Draw the vectors from the point at which their lines of action cross. What conclusion can be drawn about the direction of the change in velocity?
