Feb 25 at 12:05 comment added Albertus Magnus @nonhuman If you want the general case, then you want mass$=m$, radius$=r$, and so on, you are instead getting the highly unusual special case where everything equals 1. However, since density equals mass divided by area, or in your case $1/\pi$; you can't have mass and radius equal to one while also having density equal to one. It is contradictory as opposed to "general".
Feb 25 at 6:42 comment added nonhuman @JohnAlexiou I want the general case. That was on purpose.

I accidentally added "No energy is lost"
Feb 24 at 22:40 comment added John Alexiou Making the mass and radius equal to one and setting the density equal to one is a conflicting set of constraints that are not needed as it does not simplify the problem at all.
Feb 24 at 22:39 comment added John Alexiou If it is sliding and there is a coefficient of friction then indeed energy is lost to heat and friction.
Feb 24 at 18:12 comment added trula if you have a sliding ball on a surface with friction "No energy is lost to heat or anything like that" is impossible.It is only possible if you have no sliding so $\omega= \frac{v}{r}$
