The arrow obviously accelerates from zero to maximum velocity, but it's is extreme short order.
Yes, due to the short time the bow is stretched. But the entire time the bow is bushing the arrow forward, the arrow is being accelerated.
After that, it slows down, but quite slowly.
Again, for the comparison to rockets: The entire time the engine is running the rocket is being accelerated.
To have max thrust on a vertical will not produce acceleration after initial standing start to acceleration to reach constant velocity.
Again, stop repeating the same lie.
All the evidence shows you to be wrong and you have made it clear you have no interest in performing the experiment yourself.
A rocket will continue to accelerate while its engine is on.
You're going to have to find something better than that. It shows nothing against what I've been saying.
No, it quite clearly does.
Even without being able to tell what the acceleration is, we can easily tell that it doesn't' stop dead when the first stage finishes and instead continues moving upwards even before the second stage kicks in.
It just means that nobody is proving them to be wrong
No, it just means that you are ignoring all the proof that they are wrong.
otherwise I wouldn't still bother to argue my side.
Well you aren't really arguing your side.
You are repeating the same refuted nonsense again and again while ignoring things that show you to be wrong.
That isn't arguing a side, that is ignoring that you been refuted and pretending you are still correct.
You have provided absolutely nothing to justify your many false claims, meanwhile plenty has been provided that refutes them.
