Rotational motion from curved slope?
So I've learned for any slope with a sliding object, say a box, the speed at the bottom only depends on the height it was dropped from because of conservation of energy, assuming absence of friction ...

How do I apply the principle of conservation of angular momentum in this case?
I came across a question:
A disc of mass 2M and radius R lying in a vertical plane which is free
to rotate about a fixed horizontal axis passing from its centre. A
particle of mass M is tied to a ...
