Identical twins, each with mass 51.0 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 3.00 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?

Aww... what happened?

I will post later and share what happened.... it was a disturbing experience, though....

Frame what happened as a lesson. Think out what happened, and what it means. Then, see it as an opportunity to learn, and be prepared in the future. When you are older, you can teach your kids based on your experiences, and they win from it. Perhaps even your grandchildren will learn valuable lessons from it.
I am sorry it went badly for you, but do your best to make something good from the remains.

Thanks, Bob... I will seriously think about that.... I'll post a more detailed message tomorrow letting everyone know what actually happened
