[QUOTE="Phantoful, post: 5978762, member: 640158"] [h2]Homework Statement [/h2] [ATTACH=full]224066[/ATTACH] [h2]Homework Equations[/h2] F=ma τ = Iα = rF v=rω, a=rα L = Iω Center of Mass/Moment of intertia equations [h2]The Attempt at a Solution[/h2] [/B] So right now I've tried to model the force acting on the ring as it goes around the peg, but I think centripetal force is involved and I'm not sure how to use that in my equations of motion. A general idea I have is that rotational velocity should be highest when the hoop's center is at it's lowest possible point. Say the peg is the z-axis coming in/out of the page, the moment of inertia of the hoop should be in relation to that axis. By the parallel axis theorem and the fact that a ring's moment of inertia is usually MR[SUP]2[/SUP], it would be I = MR[SUP]2[/SUP] + MR[SUP]2[/SUP]. From this should I be using rotational energy equations or am I far off/should do something else? For B I am completely lost but I'm pretty sure I might need to solve A first for it. [/QUOTE]
