2. Han Solo and Greedo sit one meter apart having an argument in the Cantina. Both shoot their
blasters, and Greedo ends up dead. As lead investigator of CSI: Tatooine, you survey the crime scene
and query the event logs on both blasters. According to the records, Han shot his blaster 1.0 ns
before Greedo. During the argument, Chewbacca flys by in the Millennium Falcon at 0.9 c.
(a) Use the Lorentz transformations to compute the time when Han shot and the time when Greedo
shot from Chewie’s perspective.
(b) From Chewie’s perspective, who shot first?
(c) Who’s right, the cops or Chewie?
