First of all, I'm not sure where to post this.

Now, I am reading some lectures about relativity, I came quite far and understand the concept. The steps in the following I just can't follow.

"Kinetic Energy and Mass for Particles of Arbitrary Speed

For a particle of rest mass m0 accelerating along a straight line (from rest) under a constant force F, "

[PLAIN]http://img840.imageshack.us/img840/8366/relapic.jpg [Broken]

The first step I understand, but then I'm completely lost. Spend over 2 hours in figuring it out...

I know I'd have to use m= m

Can someone help me?
