Hаn Sоlо heаds frоm the plаnet Tatooine to Dagobah at 0.6c. The distance between these planets according to observers at rest with respect to the planets is 20 light-years. a) How much time does the trip take according to Han (HINT: how far is it?)? b) If Chewbacca takes off from Tatooine in another ship which catches up to Han at a speed of 0.25c (relative speed of the two ships is 0.25c), what is the speed of Chewbacca's ship as measured by an observer on one of the planets? c) If Han transmits radio waves at a frequency of 10.0kHz, at what frequency should the base on Tatooine be listening.
