Question

Two rocket ships pass overhead, traveling in opposite directions at constant, high speeds. You see that the rocket ships both cut their engines off, and by taking various measurements you determine that the two ships turned off their engines at the same time. Meanwhile, a scientist on board one of the ships determines that he turns off his engines before the engines of the other ship turn off. Which of the following is correct? Select one: a. The observation of the scientist on the ship is not valid because he is not in an inertial reference frame. b. Both your observation and the scientist’s observations are equally valid. c. Your observation is invalid because both of the ships are in motion relative to you. d. The observation of the scientist on the ship is not valid because the event of his rocket engines turning off moves along with his ship.

Explanation / Answer

Option (b) is correct Observer and scientists both are correct because we know that moving watch runs slow so scientists on a board one of the ship's determine that he turns off his engine before the engine of other ships turn off
