    This looks like homework dumping. A physics tutor is more likely to respond if you include what YOU KNOW about each problem, what YOU THINK about finding each answer.

    I don't know about Kathleen or Lauren or whatever I just had a question about this problem. I really didn't know what to do and thought maybe this site could help, but if people like this answer maybe this isn't where I should come for help.

    If you don't know about these others, why are you all using the same computer and asking similar questions about the same time?

    Ummm no one else is using this computer. I am the only one using it. It may be people from my class, because its a large lecture and the teacher mentioned this site today. Now I want to tell the professor to never recommend this site again.
