this is a physics question i am gonna ask , lets c who solves it first.

there are three people standing at the 3 vertices of an equilateral triangle of side 'a', they start moving towards each other with velocity 'v' , they constantly move towards each other until they converge at the centroid of the triangle , you have to tell:
a.)time in which they meet.
b.)the equation of path of any 1 of them (all are identical) (in any co-ordinate system .... )
c.)the no. of rotations about the centroid they make before converging.

if u answer the first one u are intelligent, if the 2nd one or third one you are either very intelligent or are an intelligent physics student.

P.S. the 2nd and 3rd part require Calculus.
if there's any way they don't then i dont know about it.

if you are able to solve the question completely then move on to a polygon of 'n' sides ....
and answer the questions in terms of 'n' and the other constants given and then take the limit 'n' tending to infinity and answer the questions in context of the circle (you have reached to taking the limit ('n' tending to infinity)).

Well done!

...but CAN you blow them into the air and gross people out?

You have to capture the bubble on your tongue and then blow gently and let the bubble roll off your tongue.

funny that you asked me that.. I practiced a lot before, and I finally did it.. but only once.
My saliva must be too viscous.

I can tie cherry stems in my mouth though.
That's a talent to have in a roomful of men, lemme tell you!

How about knotting 2 candy snakes together with your tongue?
Cherry stems, that's pretttty amazing!

Kush_ sorry we often get into these conversations, and hijacking threads... I think your physics quiz requires concerntration- something I don't have right now.
But I'll let you know if I figure out the answer!

you would like me to explain my silly thought and consequently, the desire I had to post complete drivel regarding my spit bubble?
Were you offended by my spit bubble?
Let me qualify for you the dynamic of the spit bubble.
It is ''cartoon' gesture, indicating complete lack of thought.. much like drool, on the lips and chin of one who is of little brain, when asked to complete a question that exited the mind with the swiftness that it entered the mind.
as in
*********WHOOSH************
This line represents my head
___________________________

Which means the question was over my head.


Okay for you?

I can't believe I actually had to explain my spt bubble.
I am not playing on the playground with you anymore, too many rules.

Oh yeah, my head is totally holey.

I like playing on the playground with you, SunChild... you are too sweet.
Here you are being 'chastised', and you still have the sweetness and grace to respond in a positive way.

I know if I skinned my knee, you would blow the ouchies away.
And for that, you are blessed
Don't let ANYONE tell you different. Or.. let them tell you, but don't let it resonate, let it remain a reminder to contradict all the grandness and goodness you are.

You'd be someone I'd play with too

Your kind words have truly made my day much much brighter- I have faith!!Thankyou
ALL your words are soaked with so much Love and true intentions that I could never disbelieve a word that you say, you are a true friend indeed. xoxo

I had anxiety before when I was writing in HAH, and you blew those ouchies away.
