The discussion revolves around exam preparation for a physics exam, specifically focusing on concepts related to length contraction and time dilation in the context of relative motion between two spacecraft, the Orion rocket and the Sirius crew.
The discussion is active with participants sharing their reasoning and approaches. Some guidance has been offered regarding the interpretation of the problem, and there is an exploration of different viewpoints regarding the motion of the spacecraft.
Participants are preparing for an upcoming exam and are encouraged to share their thought processes rather than seeking direct answers. There is an emphasis on understanding the implications of relative motion and the effects on measurements of length and time.

Do you have any thoughts on how to approach the problems, so you could give your ideas and people could comment rather than just giving the answers? Are you familiar with the equations for length contraction and time dilation?
Yes, that's the right approach for question (i).versaknight said:yes what i did was calculate the reltive velcocity of the orion rocket with respect to the crew of sirius and i used this velcity to find the contracted length iss that correct
versaknight said:well i don't think so beacuse for orion , sirius will be moving at the same relative speed away from him. since they have the same length, the contracted length will be the same and the time taken will be the same.. that's what i think
