Yeah, I already told you that. And relativity ...

Also, if I gave you the equation for momentum ... you'd be happy with p = m* v

However when looking at momentum of air for in-compressible air the equation for momentum needs to be expanded to

With compressible I need to expand again.

I can do the same with the drag equation.

https://en.wikipedia.org/wiki/Drag_equationYou'd be happy with

But that doesn't include relativity.

You ending up with 1000 miles per hour is the trap I set. The delta is actually only the slowing caused by friction. Say 5 mph in a light wind. V is exponential ... V^2 so you'd have been a million miles away scratching your head.

Like I said, we are done with this thread. The fun has been sucked out of it.
