Two blocks (with masses 20.5 kg and 68 kg) are connected by a string as shown. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block and machine is 0.257. Find the change in the kinetic energy of the block on the incline as it moves a distance of 15.4 m up the incline if the system starts from rest.

first, I have to set up equation for sum of force, find net force, then multiply it by the distance, right?

How is that cheat? I'm looking for a way to solve this problem.
geerky42
  • geerky42
And my way doesn't work.
anonymous
  • anonymous
So, report that problem as something you didn't solve
anonymous
  • anonymous
everything else is on the side. Understood?
anonymous
  • anonymous
are you learning physics or building problem solving skills?
geerky42
  • geerky42
I just need help, I can't figure out how solve this problem... Thats why I am here... Isn't it what Openstudy is for?
geerky42
  • geerky42
Both...?

you can't cheat, this has to be stopped. Ask this question out of your knowledge of theory.
anonymous
  • anonymous
hey @greeky42 he is just trolling just ignore him
anonymous
  • anonymous
speak to me directly, like this: Aren't you trolling now?
anonymous
  • anonymous
that's concern #1
anonymous
  • anonymous
do not assume for me. Is that clear?
geerky42
  • geerky42
And my theory is apparently wrong, and I don't know why. And it's isn't cheating. You are obviously trolling, just like Yahoo! said.

\[W = \Delta K.E\]
anonymous
  • anonymous
intial K.E is 0 brcoz the body was at rest..)

It's not *YOUR* theory, it's your knowledge.
anonymous
  • anonymous
so, it's knowledge which is wrong, theory is always there.
geerky42
  • geerky42
@Yahoo! And \[W = x \sum F\] right?
geerky42
  • geerky42
My knowledge* Better, knowledge nazi?

Sorry to interrupt. I think it's better to stop the discussion on cheating here. And also, it's okay to seek help for your homework, as long as you're looking for a way to learn how to do it, not just copying others work. @ndwelsh I think we'd better have a private talk.
anonymous
  • anonymous
what is fun about substituting numbers to formulas? Aren't you striving for better degree? What are you supposed to learn? Physics, elementary principles of expressions and variables?
anonymous
  • anonymous
@Callisto - who am I talking to now?

nw ur job is to Find Work done..By the Body on incline

Whatever you are trying to achieve in the future will unfold improperly. MARK MY WORDS NOW, bunch of puppets

\[W=F.S.\cos \theta \]

  • geerky42
@ndwelsh Like, you think I take physics for absolutely no reason? Sure... And you are here, trolling and claiming everyone is cheating... I think your life has been unfolded improperly.

  • anonymous
Or another way to approach this is find accl
anonymous
  • anonymous
Hold on there horse, don't you say "trolling" regarding my name any more? It's your stupid cheating Wikipedia type of philosophy that explains your inadequacy better than my life.
anonymous
  • anonymous
answer now, what's wrong about using reference books better than theory books?
anonymous
  • anonymous
Apparently I'm more knowledgable in this topic than you are
geerky42
  • geerky42
Yet, I don't need you, fortunately. There are knowledgable beings who are wise enough not to troll in this site and are willing to help others. What about you? Answer now. What do you do with your life? Trolling? Well, that's pathetically sad. Beside you are wasting your time.

@Yahoo! How can I find acceleration? its seems that there is not enough information.
anonymous
  • anonymous
discussing my life at this point seems to be more off the topic. --- THAT'S FOR ADMINS TO TAKE NOTE don't you SPIT THAT POISON IN MY FACE, fraking DOLL?
anonymous
  • anonymous
JUST GET THAT, CHEATER - BECOME PUNISHED FOR THAT IN FUTURE
