@maxdancona,
The angle at exit will determine the spin and momentum of hammer.
So the hammer may or may not spin on its own axis due to its causal trajectory origin.
I'd ask why the release process was so important to you, but it serves no purpose.
I am standing up, feet facing Earth, and now, like the moon, am an extension of the earth.... 1 day passes.... I am in the same spot having revolved around the Earth's axis.
I HAVE NOT spun on my OWN axis..... It would be a NOTICABLE 360` turn, I assure you.
