Halliday, Resnick & Walker β€” Relativity: Problem 19

19 Galaxy A is reported to be receding from us with a speed of 0.45c. Galaxy B, located in precisely the opposite direction, is also found to be receding from us at this same speed. What multiple of c gives the recessional speed an observer on Galaxy A would find for (a) our galaxy and (b) Galaxy B?

πŸ“ Solution Approach

Find: (a) our galaxy and; (b) Galaxy B?
