A physics professor is pushed up a ramp inclined upward at an angle theta above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and chair is m. He is pushed a distance x along the incline by a group of students who together exert a constant horizontal force of F. The professor's speed at the bottom of the ramp is v.

Use the work-energy theorem to find his speed at the top of the ramp.

I know W=K2-K1 and K=.5mv'2 but i dont understand

would it be K= .5mv'2 sin(theta)

I also know F=-kx but how would i equate that for this problem/

please help!

A month ago I met a great guy; we clicked instantly & 1st date lasted hours. It was amazing how comfortable we felt w/each. He told me he wasn't playing games, this could b special & didn't want to jump into anything 2 quickly -he wanted to get 2 know me better. Our 2nd date was as great -we spent all day 2gether The whole time held hands & cuddled. In shops he held me close, held my hand & hugged me. We went back to mine & had a great kissing session but still decided to wait....but he wanted me 2 play w/him. In between our dates we constantly texted each other & chatted on phone. His text 1st flirty; then naughty....on our 3rd, we still had amazing convos & laughs but he seemed distant & reluctant 2 hold my hand or cuddle. After the date he didn't text. I waited a couple days then text him- his reply asked why I was quiet. I replied "I sensed u needed space & stepped back 2 give it 2 u-u r amazing & I don't want 2 crowd you xxx". I haven't heard from him since. What happened?

A man goes to his doctor for a complete checkup. He hasn’t been feeling well and wants to find out if he’s ill. After the checkup the doctor comes out with the results of the examination.

“I’m afraid I have some bad news. You’re dying and you don’t have much time,” the doctor says.

“Oh no, that’s terrible. How long have I got?” the man asks.

“Ten,” says the doctor.

“Ten? Ten what? Months? Weeks? What?!” he asks desperately.

“Nine. . .”

Limit as x-->infinity of sqrt(2x^2+1)/3x-5
This is an example in my book and they've divided numerator and denominator by x and then it became Limit as x-->infinity of sqrt(2+1/x^2)/3-5/x

I don't understand why the numerator is sqrt(2+1/x^2). Please explain. That's all I need to know. Thanks.

My best friend is lesbian and she is not American. She is here to visit me. In her country, homosexuals are hugely discriminated and even physically abused. I want her to stay in America, legally. How does one go about it? Is discrimination and abuse based on sexual orientation good reason to make her get legal status to stay here? Any info will be appreciated.
Thanks!

you believe them, but if there is a "wet paint" sign somewhere, you have to touch it to make sure?

Im not great at making friends. I have made friends with a guy in work since aug. The thing is i cant tell if he sees me as a mate. Hes not the best at contact. I email him and he does reply and is jokey. The thing is when he wants to do stuff its always can u call/text me. He nagged me to go over his new flat which i did and he said i can go over anytime and we met up for drinks. He says im a cool person. Weve gone to lunch 4 times he asked first so i just returned the favour. The one time i was down he emailed me to make sure it wasnt him who offended me also when i emailed him once he didnt reply he did come to see me in my department to appologise for not replying

Here my take:

Our Solar System is just one of 100 billion of them in the Milky Way Galaxy. Our galaxy is just one of 35 or so in the local group. The obserable universe if believed to have BILLIONS upon BILLIONS of galaxies. So even life in the universe only comprises %0.0000001 of the star systems out there, that would still be millions of worlds. That being said, I think it's the height of arrogance that anyone would make an assertion that we're the only civilisation that exists.

BUT..

The NEAREST star system besides us is Proxima Centauri, which would take 4 years or so to reach, IF YOU WERE GOING THE SPEED OF LIGHT. Additionally, it would take 100,000 years to exit the Milky Way, millions of years to travel to other galaxies, and billions of years to travel to the other side of a universe that we can't even place boundaries on.

Plus, at one tenth the speed of light (around 100 million km/h),
(hold on, out of characters...)

I am not a JW but I wonder why so many people get so angry.I read about Jesus,it is clear that he went all over teaching.That is throughout the NT.That angered people that he taught what they did not believe to be true,they had their religions but he didn't give up.To the point of death from those who said he had no right to claim such things.Jesus was a false prophet to them.JWs are doing the same thing.Why the strong anger, hatred?They want to share what they believe can save us.It is true love & belief in Bible & what Jesus taught,knowing they will be laughed at,treated bad,they spend days & cont. as Jesus did.In the Bible Jesus says for all to spread the word! For the truth to be heard everywhere.JWs are the only ones I see doing this in UNITY.Jesus, Noah, people laughed,said they were were telling lies,sinners,not of God.JWs remind me of those stories in the Bible. Others sent by God but people didn't listen,they were even angery.It is like the Bible stories I've read,but 2007.
