need help T_T

OpenStudy (somy):

i don't get why it's D T_T @thushananth01 @KissMyAxe

OpenStudy (anonymous):

Somy its A

OpenStudy (somy):

ah yeah lol A

OpenStudy (somy):

@jmcs1985

OpenStudy (anonymous):

why don't u find the angle b/w the R.f and the horizontal force and you'll see that A is the right answer

OpenStudy (anonymous):

@KissMyAxe Are you sure we have to manually measure?

OpenStudy (anonymous):

LOL no! use sinx= opp/hypo..

OpenStudy (jmcs1985):

Hi @Somy, @KL-RC! This one is a resultant force problem by adding the vectors together - head to tail, then finding the resultant using the Pythagorean Theorem. |dw:1402417808263:dw| Then it looks like this by attaching head to tail.... |dw:1402417935907:dw| To find the resultant, you use the following formula\[Resultant = \sqrt{\left( F _{x} \right)^{2}+\left( F _{y} \right)^{2}}\]So, \[R =\sqrt{3^{2}+4^{2}}=\sqrt{25N^{2}}=5N\] The position is based on the fact that the disc is being moved from the center and outside. I hope this helps! Let me know if this makes it better. JMC

OpenStudy (jmcs1985):

@KissMyAxe, good idea for proceeding forward, although not necessary. Don't stop thinking outside the box!!

OpenStudy (somy):

dear helpers please read the question @KissMyAxe @jmcs1985 lol

OpenStudy (jmcs1985):

oops

OpenStudy (anonymous):

what Somy? KL-RC understood it!

OpenStudy (somy):

my habibties @KissMyAxe @jmcs1985 listeeeeeeeeeeeeeeeeeeeeeeen i know this thing what im asking for IS SHORTCUT

OpenStudy (anonymous):

I gave u a shortcut find the angle!!

OpenStudy (somy):

wth i know it without u telling me >_<

OpenStudy (somy):

ughhhh never mind it =P

OpenStudy (anonymous):

whats the angle than?

OpenStudy (jmcs1985):

@Somy, @KL-RC, @KissMyAxe - I think that this can be worked using elimination. A and C are essentially the same answers, so they both can go. Now we are left with B and D. Since the Fx is greater than the Fy by one Newton, the pulling power will be more towards the right, and not the top. Since the vectors are not equal, they do not originate at the center. That's why it's D. Is that better @Somy ?

OpenStudy (somy):

lol its A actually

OpenStudy (jmcs1985):

So it is A. Funny! ;P

OpenStudy (somy):

omg im sorry guys im just gonna use Pythagoras as i thought before

OpenStudy (jmcs1985):

Here I was going Vulcan of why it would be D.

OpenStudy (somy):

lmao im so sorry that's my mistake @jmcs1985

OpenStudy (jmcs1985):

@Somy, no worries. Just a lot of head scratching on my part.

OpenStudy (anonymous):

did u get anything?

OpenStudy (somy):

=_= man i told u i know this thing so there is nothing to get i just thought there might be a shortcut way of doing it

OpenStudy (anonymous):

Oh!! sorry no shortcut

OpenStudy (somy):

yeah i figured that much

OpenStudy (somy):

for Gods sake physics why don't you once become easy for me? ε=ε=┏( >_<)┛

OpenStudy (jmcs1985):

Don't worry - we have all gotten that feeling. @Somy, @KL-RC , @KissMyAxe , the closest thing to a shortcut, is to remember the 3,4, 5 triangle. You have 3, and 4, so the R had to be 5. The direction and location would be determined by where the largest force is eminating.

OpenStudy (jmcs1985):

@Somy, is that more in line of what you need?

OpenStudy (anonymous):

LOL

OpenStudy (somy):

i solved it anyways thank you guys :) u beautiful shuttup @KL-RC

OpenStudy (anonymous):

You're more beautiful senorita @Somy

OpenStudy (somy):

no again my beauty is no match with your's @KL-RC

OpenStudy (anonymous):

I'm nothing against your beauty @Somy

OpenStudy (jmcs1985):

All of you are, and also very intelligent. @Somy @KL-RC @KissMyAxe . Are you more of the hands-on learner, @Somy ?

OpenStudy (somy):

lmao @KissMyAxe you are beautiful too

OpenStudy (anonymous):

not just beautiful, VERY beautiful

OpenStudy (somy):

@jmcs1985 well we have our own ways of learning to make it fun and enjoyable lol

OpenStudy (anonymous):

@jmcs1985 you are very VERY undeniably beautiful.

OpenStudy (somy):

@KL-RC u killed me LOL

OpenStudy (jmcs1985):

Hahaha, *bows* thank you, same to you @KL-RC . @Somy - the reason I ask is because I went through the same thing with physics, it's just practice, practice, practice. @KissMyAxe - you are also part of the "very, Very undeniably beautiful" list, too. Keep up the good work!

OpenStudy (somy):

okay lets open 'very, Very undeniably beautiful' club

OpenStudy (somy):

members @jmcs1985 @KissMyAxe @KL-RC and me

OpenStudy (anonymous):

it shuld be pythagoras theorom, and the resultant force lies to the more force side, in this case 5N is more towards 4N

OpenStudy (somy):

owh so it'll lean to the longest? in this case 4

OpenStudy (anonymous):

yup

OpenStudy (somy):

OMG here you go my SHORTCUT i love your brain @thushananth01 brilliant!! wanna join 'very, Very undeniably beautiful' club?

OpenStudy (anonymous):

*facepalm*

OpenStudy (jmcs1985):

@Somy for President! with @KL-RC as VP. Lol. Take care to all of you..

OpenStudy (somy):

okaaaay Good luck in tomorrow's exam guys!!!!!!!!! let's have crying meeting tomorrow after exam

OpenStudy (anonymous):

lol
