英文相对论物理题.
Intergalactic space travellers need to know the relative velocities and masses of their
space ships.Each ship,therefore,has a 1.0 m long bar painted on the side of the ship
alongside their rest mass.as you pass by a ship you measure this 1.0 m bar as 0.93
m.What is your relative velocity?You also observe their ship measure for printed as
365,000 kg.What is their mass relative to you?What does an observer in the other
ship measure for your 1.0 m bar?

需要知道星系之间的运动物体的相对速度以及他们所在太空船的质量,在每艘船的边上画上1米长的棒子,当你经过这首船时,这个1米物体的测量结果是0.93米,那么你的相对速度是多少?此外,你发现其他船上所画物体重为365千克,它们的相对质量又是多少?其他船上的观察者观测到你所在船上1米的物体时,长度为多少?
PS：你这里的相对速度和相对质量我不知道是不是求比值,因为你这没给出船的速度,假设船的速度为Vo, 由计算公式得：0.93=1* 根号下1-V的平方除以Vo的平方,算出V就是相对速度
同样的算相对质量,由上面的V/Vo,代入公式：365=M*根号下1-V的平方除以Vo的平方,求得M就是相对质量了
最后一样的代公式：L=1*根号下1-Vo的平方除以V的平方,这里要把速度换一下,不是你观测了
（有的公式不好写,希望你看得懂,公式随便一本书上都有,就是时间变慢或者长度变短之类的,套上去就是了,以上过程仅供参考)

先翻译下可以吗 不然放到英语那边 让人翻译的再放到物理这
