I am having trouble with this homework (yes homework question). Our teacher just threw it at us and hasn't explained it. It is ok if you would just like to explain how to go about it; that would be great so then I can actually learn how to work the problem. Thanks

I was wondering if kinetic energy is conserved during elastic collisions like when friction is not involved and neither is any other resistance. I was wondering if it was conserved if one object was standing still and the other hit it and also when both were moving at each other.

I was wondering how you would apply E=MC^2 to a physics problem. The problem is asking for the maximum mass of a rocket that can reach an altitude of 345 km. It can convert 1 g matter into thrust energy by E+MC^2. I admit this is a homework problem so you don't have to give me the answer but just simply how to start working it. My teacher did not go over this and I can't find it in my book. Thank you in advance.

My uncle just told me that my cousin has a couple of cd's out as a rapper. He is from Texas and I was wondering if anyone had heard of him before. I am not sure if it is little J or lil J.

I was wondering if you had to take any training or if you just respond to the ads I see in the newspaper or what? Also does anyone know of anyone who has made good money doing this.

I am suppose to go with a college church group to camp starting Friday however my aunt is dying of cancer. My family did not go on our vacation last week because the nurse told us that she would probably die last week. I really want to go to the camp because it will be an awesome opportunity however it is like 14 hours away. i feel like if I go she may pass while I am there and I will not be able to get home, however if I don't go I feel like she will still be hanging on come next wednesday when I am scheduled to get back. Either way I feel like I will regret my decision. What would you do in this situation?

I have just started Tae Bo with Billy Blanks and I was wondering if anyone had any success stories or heard of any successes.

Everytime I try to send an email containing pictures to anyone, a blank white box appears instead of the picture. I am not sure why. It does not seem to matter what computer I am on either. Do I have some kind of setting that is set wrong or what? What do I need to do to fix this?

I am a sophomore in college and I already work during the week at a daycare. I need to get a little more cash and would like to work somewhere on the weekends. Does anyone have any suggestions? Do restaurants hire college students just for the weekend? Thanks

I am a sophomore attending a private university and have applied for many scholarships and also the fafsa.

I am in college and need a new haircut to help me look and feel out of high school. Right now I have longish brown straight hair. It is a little on the thick side and gets frizzy with humidity. I do not want to go shorter than the shoulders and I want a cut that is easy to maintain. I part it on the left side and I have an oval face shape I think. Does anyone know of any websites with good pictures of hairstyles? Or could you describe a cut or suggest a celebrity with a good cut? Thanks.

I read several weeks ago in TV Guide that Grey's Anatomy is moving to Thursday nights at 8 pm central time. Has anyone heard that too? What do you think of that? Do you like the time it was alreay on? I like it on Sunday nights.

My neighbors dogs are about 20 ft from my bedroom window. Many nights the dogs bark and keep me awake. The pin which they are in is between MY privacy fence and their house. We have asked them numerous times to do something. Once they moved them to the other side of their trailer but they moved them back shortly. We have threatened to call the cops but they would not do anything even if we did (we already checked). What should we do? Some of them are muts and some are pit bulls.
