There's 2 things needed to create the whip effect. The first thing is to be loose as I explained.
Let's say you're holding a whip. You would CRACK the whip and know what to do with your arms. Would you wave your arm up and down like those guys ringing the bell during xmas time? No, it wouldn't work. Same with doing the cobra strike. You would use a FLICK. If this concept makes sense, then you should be able to apply it to the serve (or throw) now.
Really, this whip concept goes by other names. This is the kinetic chain. What is happening is one body part is accelerating and moving. Then it needs to STOP moving to give all its energy to the next link in the chain. With the cobra strike, it's easy to understand how this works. There's fewer moving parts. You move your forearm using your elbow joint while your wrist stays relaxed. You use a flick to start and stop. And that's it.
You need to understand and internalize this kinetic chain concept. It's nothing new and people bring it up a lot to generate power on the forehand, serve, etc. To summarize:
1. Stay loose
2. Transfer energy to next link
