In episode 5 of Star Wars the Empire’s spaceships launch probe droids throughout the galaxy to seek the base of the Rebel Alliance. Suppose a spaceship moving at 2.3 x 10⁸ m/s toward Hoth (site of the rebel base) launches a probe droid toward Hoth at 2.1 x 10⁸ m/s relative to the spaceship. According to Galilean relativity:

(a) What is the speed of the droid relative to Hoth? 

(b) If rebel astronomers are watching the approaching spaceship through a telescope, will they see the probe before it lands on Hoth?
