in question a) I don't get where does come from M(v0+v)! i did the law of conservation of momentum before=after. i got that 2m is equel M, but i think it is wrong! in b) i assumed before collision that Lrot is 0 and Ltrans= r(M) x p(M). and after collision i was thinking that Ltrans=r'(M) x p(M)...

Two point-like particles of mass m. The particles are rigidly connected to each other with a mass-less rod of length L. The particles are initially at rest in such a way that one particle is at the origin and the other is at the point (0, L). A point-like particle of mass M collides with a...
