Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Can someone tell me what to expect and how to calculate the length contraction when two bodies move towards each other, rather than away?

The particular question I'm stuck on is this:

A garage is 5m long, a car approaches it at 0.6c. What is the length of the garage according to the car?

I know the length would be longer in the car's frame if it was movingawayfrom the garage, and I could calculate by how much.. but what happens when the car moves towards it?
