一道相對(duì)論的英文物理題,求上過(guò)大物的可以進(jìn)來(lái)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.

優(yōu)質(zhì)解答
先選題中那個(gè)靜止的參考系為參考系,那么spaceship的長(zhǎng)度就應(yīng)該是L=350*根號(hào)（1-（0.82C）^2/C^2）=自己算一下哈~,然后t=2*0.82C/L,最后再用相對(duì)論的時(shí)間公式把這個(gè)參照系的t換算成那個(gè)Spaceship上的t就可以了~
