twice of that

ok thanks

how do i find it ? and which case should i take?

How do you know centripetal force will max out at top , As component of centripetal force does increase will increasing theta , but velocity goes down .

I found after integrating the acceleration that velocity is not uniform , it is somewhat falls exponentially wrt to theta .

In these attachments , I have taken two cases , or you can call two different assumptions . In case I , I considered , the axis of rotation as the com of ring and only one centripetal force will act that is on the mass attached to its rim . In case II , I took to the instantaneous axis as my...

this is the last part

Ok , here are the attachments which show my incomplete soultion .

hello omc1 , If you notice momentum will remain conserved along horizontal axis . ie component of velocity along horizontal axis will remain same throughout . So it will not cause any change in momentum . Then what will cause a change in momentum ? When you project the mass upward , the...

anyone?

This is the attachement

Hello everyone , I recently encountered a question in my Russian physics book . I did a lot of brainstorming with this question , I couldn't reduce the eqauation in one variable though . The question is Homework Statement The problem is marked yellow in the attachment . Please note the...

ok I make a new thread , regarding this post

Does that mean the velocity of center of mass remains v throughout ?

Ehild , Can you please explain further why centripetal force would be max at top , I deduced an equation which give velocity minimum at top . And centripetal force is proportional to velocity .
