1. ### suppose a spaceship of length Lo is traveling at a high rate of speed v relative to an observer.?

... because c = 3 . 10^8 m/s and so the relativistic shrinkage is not usually very much. At 50% the speed of light ( c / 2 ), the shrinkage is quite pronounced L ( shrunk length ) = Lo ( static length) . √ (1 – ( c /2)^2 / c ^2...
