    Ball Rod System
AI Thread Summary
The discussion focuses on finding the center of mass (CoM) of an L-shaped rod and a ball system. Participants suggest treating the L-shaped rod as two separate rods to simplify the calculation of the CoM. There is a request for more details about the homework assignment, including dimensions and mass values. The importance of seeing the entire problem is emphasized, as it may not always be necessary to find the CoM. The conversation highlights the need for clarity in physics problems to determine the best approach.

I suspect we can treat the L shaped rod as two rods and then find the com for that system and then find the com of the ball and that system

Yes!

or you could find the com of one of the rods and the ball, and then find the com of the 1st system and the other rod,

or better ...

Welcome @March !
Could you post the full homework and your attempt to solve it?
Have you been given any dimmensions and values for each mass?

It is often unnecessary to find a CoM. We need to see the whole question.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
