That's a shock to me, but I will accept it. I'll try to solve the next questions then. You've been a very big help, so thanks a bunch.

So would you say that my way of solving the two questions is correct? I'm sorry to look for such a binary answer, but I can really not tell if I'm understanding this right. How would you have solved the first question, if that was the only one presented to you?

I would very much assume it is, since nothing else has been said. I don't know if I made it clear that it is a completely inellastic collision and the stick the ball is attached to has a mass, if this has anything to do with it. With regards to finding the velocity, if L_before = l*M*u and...

Are you trying to solve for the speed here? In case you are, I think you might also have taken a few steps I don't understand. I understand there is a connection between angular velocity and velocity/radius, but there are still some elements missing. I would also like to point out that...

I was much surprised at how close you were too. I think you might be right about the two last questions, but I've not looked on them, considering I can barely manage to answer the first one. Does this new information provide any insight in what I'm doing wrong?

The question after this sounds: "Determine the velocity, v, of the two balls immediately after collision, expressed by m, M, l, and u." I didn't add this question, because the two are defined within their own "questions", but I'm sorry for not adding it. To make sure that I deliver all the...

You have me absolutely stunned here with that question, since I believe that I already made this clear. Apparently I don't even know what I'm asking. I'll try to explain what I've done until now. The angular momentum before the collision, with regards to the point P, must be L = l*M*u...

Can you guide me in a direction as to how this is solved then? Are there any identities that I'm not taking into account when I simply equate the angular momentum from both before and after?

That works too, I think. I'm not so sure what the difference between the two questions is, but I can try to make the question again: "Specify the collected angular momentum for the system consisting of the two balls and the stick with regards to the point P, both before and after the...

It's in another language originally, but I assume this is what it would translate to. Does it sound odd?

Homework Statement A homogenous, thin stick with the mass m and the length l is hanging from the ceiling and can rotate freely around the point P. A small ball with the mass of M is attached to the end of the stick. The small ball on the end of the stick gets hit by another small ball with...
