Your example was about an elastic collision and not about a centripetal force.
Your big misconception is that you have got it in your head that a perpendicular collision of a moving object cannot change the speed of that object, which is wrong. You seem to have gotten that impression because of how a centripetal force works. I will say the obvious once more; a collision and centripetal forces are 2 different things.
Perpendicular force does not change the magnitude component of velocity. it changes the direction and only the direction.
What is the difference between something that does not happen, and something that can only happen if you do something impossible?
Is there really no one reading this with the courage to call this Naked Science King out on this nonsense
Well, here's my take on it:
Let's do a quick check to see who is talking nonsense.First and foremost we know that in an elastic collision the KEi = KEf.
Centripetal force is associated with circular motion.
by a single but large impulse the centripetal force acts, and brings about that the body deflects from the line Bc and goes along in the line BC
The diagram shows a blue ball traveling at a velocity of A-C, which is struck by a red ball traveling at a velocity of B-C.The Blue ball is deflected with a resultant velocity C-D,

This is a straw man.
In the passage from Newton's Principia,
You refer to collision as if it were some special force, with strange properties.
You refer to Halc?s ?experiment? as conclusive proof. He has not performed any experiments.
if you can, and answer the very simple question.Perpendicular force does not change the magnitude component of velocity. it changes the direction and only the direction.
Teach me O guru of science
Your force is not being applied perpendicular to the motion of the body in question.
