A 15.0 kg object moving in the +x direction at 5.5 m/s collides head-on with a 10.0 kg object moving in the -x direction at 4.0 m/s. Find the final velocity of each mass if:(a) the objects stick together, (b) the collision is elastic, (c) the 15.0 kg oject is at rest after the collision, (e) the 15.0 kg object has a velocity of 4.0 m/s in the -x direction after the collision.

I have the answers, but I dont understand how they were derived: (a) 1.7 m/s for both (b) -2.1 m/s, 7.4 m/s (c) 0, 4.3 m/s (d) 2.8 m/s, 0 (e) -4.0 m/s, 10.3 m/s

It doesn't matter if you can't get all of them. EVERY little bit helps.

No offense but I have seen the answers you have given in the past and you are not too informative.

The World's Greatest Cowboy was captured by some Indians, who told him they would burn him at the stake at dawn, but because he was the World's Greatest Cowboy, they would give him a last request.

The World's Greatest Cowboy said, "Let me talk to my horse."

So he whispers in the horse's ear, the horse runs off, and returns in an hour with a beautiful redhead. He takes her into a teepee and makes love to her for a couple of hours. Finally she staggers out, gets on the horse, and rides away. An hour later the horse returns.

The Indian chief says, "Now we know why you are called the World's Greatest Cowboy! That was a good horse trick, and we are good horsemen ourselves. We will give you another last request."

The World's Greatest Cowboy asked to speak to the horse again.

The horse runs off, and returns in an hour with a naked, beautiful, to die for, knock you off your feet blonde. The World's Greatest Cowboy takes her into the teepee and after three hours, she staggers out and has to be helped onto the horse, which carries her away and returns in an hour.

The chief says, "The tribe is impressed, not only by your horse, but by your stamina and ability! Now we are certain why you are called the World's Greatest Cowboy, and are a great and honored enemy. We honor you, and we must still kill you at dawn, but we will still give you one more last request."

The World's Greatest Cowboy walks up to the horse, grabs it by the head, and giving it a shake, says, "Posse! I said go and get me a POSSE!"

Yesterday I turned on my computer, brand new as of 3 weeks ago and It would not boot up. It gets to the stage where the windows loading bar appears and then the screen goes black and puts itself on standby. The computer remains on, doing nothing. It works on safe mode, I have tried system restore and Virus scanning. I used AVG and Reading error, Boot sector of disk comes up. But the program does in no way act to solve it. Only after I hit reset, after it has shut itself off (well seemingly the screen goes black) does it give me the option to swap to save mode, today it even asked me which OS I wanted to use, there is only Vista on here. This could well be a virus, as my limited knowledge of computers causes me to assume. I also tried CCleaner and ad-aware. No luck with anything. This problem has caused me much distress as I have no funds to buy other programs or the help I need to fix my computer.

Thank you ever so much for your kind help.

My latest kitten - a 9 week old tabby persian - was brought to me with fleas. I have used stronghold spot on treatment and today have noticed a few dead fleas on her blanket. I'm teaching her to lie still to be combed as she'll need it doing for the rest of her life as a persian but I'm wondering if I can use a normal nit comb to remove any more dead fleas/eggs or would it be better just to shampoo her?

Assume:
I am a forward looking blue collar worker. Myself and my wife have set aside $2,500 every year from the time we were 18 until we are ready to retire at 65. I have earned the historical average stock market returns, and am now sitting on ~$4.7 million.

By your definition, do I qualify as an greedy rich fat cat investor, who deserves to be taxed at a higher rate, seeing as how I'm not "technically" (in your words) earning the dividends and capital gains I am now living on?

My son is getting married and he and his future wife do not want to register for any gifts. They have been together for a long time and do truely have everything they need. Instead they would like to set up something called a "money tree." They have said they do not expect the guest to put money in if they don't want to. But registering for things they do not need seen silly to them. I have been informed they do not want to be put in the same situation as my oldest daughter. I was told my oldest registered just to make me happy and to shut me up. Apparently she did not need anything either. And I also found out they had a yard sale and over half the gifts they received were sold because they did not need them. I've been told this money tree is at a lot of weddings. Maybe I'm just to old fashion. My son and daughter inlaw are good people. They never asked for anything not even a dime for the wedding. Should I keep my mouth shut and let them do as they wish?

My family is quick-witted, fairly intelligent, and not challenged by many board games... but we love board games and want to be challenged by them or entertained or both. Games that require a sense of humor or puzzle solving skills are a plus. And, we also like games surrounding pop culture. We have many board games and word games, but we're always on the lookout for more. (Examples of what's in our game closet: Apples to Apples, In Other Words, MadGab, Catchphrase, Cranium, Trivial Pursuit (in many forms), Pop5, etc.) Have one that you and your family and friends can't pass up? Have one that entertains you for hours? Have one that you "get" that others might not "get" because they require extra thinking? Please suggest your favorites - even if they aren't so new to the market or if they are difficult to find. Thanks, in advance, for your help. This information will be very useful for Christmas.
