Sorry I'm just still really confused. "v" is the x-velocity of the rocket right, so 0.6c? Then what are Ux and Ux'? Is Ux' the transformed velocity into our frame? But then what is Ux, surely that's the same as v?

Here's the question:
"A rocket is traveling at 0.6c, v, along the x-axis relative to you...
