(sigh) Have it your way...I will just continue to shame you with facts. Actually, you will just shame yourself by ignoring the facts that I present.
In fact I would ask you to independently calculate the values for the hypotenuse yourself. Each successive value increases at a changing rate. That's a fact that I can not deny.
I am not questioning your calculations. They are correct. It is not that math that is wrong, it is your interpretation of what they are telling you that is wrong. I have explained (but perhaps you did not understand) that the changing rate is due to Pythagorean Theorem being based on the AREA of a triangle.
And I'm not quite understanding why you refuse to accept this fact.
Fundamentally, it is because the object you are trying to calculate the velocity and acceleration for (the mass) DID NOT TRAVEL ALONG THE LINES OF THOSE HYPOTENUSES. Kinematics of an object are based on the path the object traveled, and velocity and acceleration are time derivatives of that path. Your use of the hypotenuses is an incorrect method to calculate the acceleration of the object. Understand this: The hypotenuses do NOT describe the path of the object, hence they have nothing to say about the acceleration of the object.
The hypotenuse acceleration is along the same direction that the centrifugal force was on.
No it is not, because that force is no longer present. The force was imparted by the string. Once the string was cut, that force (which induced the curved path) ceased to act on the body. So the last time that force was present it was NOT AT ALL acting along any one of your hypotenuses. It was acting at a 90 degree angle to the tangent path that the mass ended up following.
Again....Your analysis is wrong and you should feel shame that you are not seeking to understand why what I am telling you is the actual truth (and the math backs me, not you).
Making it identical in behavior to gravity.
Wrong again. I will not even address any of the rest of your fallacious discussion beyond this statement of yours above. Because it is all conjecture based upon incorrect analysis, just like the analysis you gave above is incorrect. You are not doing vector dynamics correctly. Your refusal to understand how to do it correctly, and thus not admit your error, is what holds you back. But of course that same refusal is what feeds your belief that you have discovered some truth that no one else did. But it is not a truth. It is delusion, and nothing more.
