1. Homework Statement
Two identical spaceships,each 200 m long in its rest frame pass one another travelling in opposite directions.According to a passenger in one of the spaceships,the relative velocity of the two spaceships is 0.58c.


2. Homework Equations



3. The Attempt at a Solution
What the length of each spaceship in a reference frame in which both are of equal length?

you need to have a go at the problem yourself, before we can offer advice. think about what equations you need to use.

I don't know but it may be length contraction.

A "reference frame in which both are of equal length" is one in which the two space ships have the same speed. What would that be?

yes. The problem is about length contraction. And as HallsofIvy is saying, you need to work out what is the transform to a frame where both ships are travelling at same speed. Then you can use this to work out what is the length of the ship in this frame.
