Question

) A spaceship whose rest length is 280 m has a speed of 0.79c with respect to an asteroid. A comet, with speed 0.82c with respect to the asteroid, passes the spaceship traveling in the direction opposite to that of the spaceship. What is the comet's speed relative to the space ship?

Please use the following formula I've attached also as the second photo, will rate! thanks!

Basically I have a solution of my own for this but I'm unsure if I was right and I cannot wait to know if I did it correctly so I was hoping someone could show me the right solution to this problem.

Answer 1

The comet's speed relative to the spaceship is 1AB (0.79c)+(0.82c) (0.79c) (0.82c) 0.98c
