hi, im having a little trouble figuring this problem out.(adsbygoogle = window.adsbygoogle || []).push({});

Two particles in a high-energy accelerator experiment are approaching each other head-on. Each has a speed which is f times the speed of light, as measured in the laboratory. What is the magnitude of the velocity of one particle relative to the other? Give your answer as a fraction of the speed of light.

I belive that you will have to use the lorentz velocity transformation equation which is v_1= v_2+u/(1+u*v_2/c^2) . but the answer doesnt involve u so im not sure where to go with this problem.

thanks
