Where did the value of V and 600 come from in this formula?

V is the unknown. 600 ohms is the approximate ball park feedpoint
impedance for a traveling-wave antenna.

I'd like to be able to calculate the voltages also for let's say my 5 watt QRP rig.

Remember, it is a really rough estimate. For 5w, V^2/600=5w, so
V ~ 55v RMS. The peak voltage at the end of a dipole fed with 5w
would be very roughly 150 volts.
