As a space station commander, you see two rockets traveling to opposite ends of the galaxy. Rocket A is traveling at 0.800c and rocket B is traveling in exactly the opposite direction at 0.700c. Will A and B each claim that the other rocket is moving at a speed greater than c, relative to their own reference frame (rocket)? How will the rate of increase of the distance between them according to you compare to the rate according to the rocket pilots? Explain.
Answer to relevant QuestionsEvents A and B happen on your x-axis. They are separated by 500 m. You observe that A occurs 1.00 μs before B. Could A have caused B? Explain. A person 1.20 km away from you fires a gun. A wind is blowing at 10.0 m/s.
