i.e 1/2(c)

If we get two bodies of 1/2(c) speed then by moving these bodies in opposite direction the spees of light is attainable?

Is it possible?

[tex]w=\frac{u+v}{1+\frac{uv}{c^2}}[/tex]

With u=-0.5c and v=0.5c, you get w=c/(1+0.25)=0.8c.

Is from this equation the velocity of light is attainable or not by the motion of two bodies having speed less than C

It's not. If u<c and v<c, then w<c.

The 2nd postulate says that all observers measure the speed of light to be the same

So it doesn't matter to me how 'fast' any other object is traveling, I always measure

A consequence of this idea is that, as stated above, the (relative) speeds of individual moving objects does not add algebraically.

yes. Fredriks answer is precisely correct as observed from either u or v,

but if these are the speeds of spaceships relative to earth, an observer will see the ships moving apart at speed c....but if each ship emitted light, the light from each would be observed at speed c among all observers....
