Angular momentum and conservation of momentum problems

[lucianb]

I got these problems from my teacher, my physics teacher of course, they're about angular momentum, conservation of momentum etc. The problem is that i have no ideea how to even begin solving them. If there is anyone out there who thinks that he/she is good in physics can u give me a hand. I really need some help.
