一道相对论的英文物理题,求上过大物的可以进来解答一下.
a spaceship whose rest length is 350m has a speed of 0.82c with respect to a certain reference frame.a micrometeorite,also with a speed of 0.82c in this frame,passes the spaceshi on an antiparallel track.How long does it take this object to pass the spaceship as measured on this ship.

先选题中那个静止的参考系为参考系,那么spaceship的长度就应该是L=350*根号（1-（0.82C）^2/C^2）=自己算一下哈~,然后t=2*0.82C/L,最后再用相对论的时间公式把这个参照系的t换算成那个Spaceship上的t就可以了~
