[QUOTE="jselms99, post: 6868963, member: 734621"] [B]Homework Statement:[/B] Okay guys I’m lost: I have a train measured as being 100 meters in length standing in the station. Once its pulled out and it reaches a constant speed, the length measured by observers who are alongside the tracks is 50 meters. How fast is it traveling? I have to calculate this for different distances; for example, 10 meters, 50 meters, 100 meters and represent the answer as a fraction of c. [B]Relevant Equations:[/B] The problem is, I don’t know what equation I should be using! Okay I’m assuming I have to use √1- v^2/c^2 multiplied by some coefficient of length but I don’t understand any of this and could really use help understanding the process and/or reference material that might point me in the right direction [/QUOTE]
