The Empire Strikes Back
The starships of the Solar Federation are marked with the symbol of the Federation, a circle, whereas starships of the Denebian Empire are marked with the Empire's symbol, an ellipse whose major axis is n times its minor axis ( in the figure ).
How fast, relative to an observer, does an Empire ship have to travel for its markings to be confused with those of a Federation ship? Use for the speed of light in a vacuum.
an Empire starship must undergo relativistic contraction by factor n to be confused with a federation starship.
You should have a ...
