Question

Two spaceships approach each other with velocities .9c.Acc to observer on spaceship what is velocity of other ship

Answer 1

Answer:

Special relativity, developed by Albert Einstein, applies to situations where objects are moving very quickly, at speeds near the speed of light. Generally, you should account for relativistic effects when speeds are higher than 1 / 10th of the speed of light. Relativity produces very surprising results.
