Now then, this is a past paper question for only 3 marks but its annoying me.(adsbygoogle = window.adsbygoogle || []).push({});

2 identical spheres undergoing an elastic relativistic collision. The spheres move with a speed such that their CM frame kinetic energy is equal to their rest energy. Calculate the speed the spheres in the CM frame.

Not entirely sure about this, i took the obvious option and calculated (root3/2)c as my speed.

Any ideas?

Thanks
