i consider myself somewhat of a physics geius, if anyone else here likes physics, you should try the problem below:

A force of 75N(newtons) is applied to a 30.0kg object at an uppward angle of 50.0*(*=degrees). The object moves with a constant velocity of .500m/s. What is the co-eficient of kinetic friction betweeen the object and the floor?

givens:
Fa(force applied)= 75.0N @ 50*
M(mass)= 30.0kg
a(acceleration)= 0m/s

if anyone else has any physics questions or problems to give my, ill try them out for fun and see if I cant help you!

Can you answer any other kind of questions?

I'm curious.

hmmmm..... ok so like these 2 atoms were walking down the street and then one turns to the other and says "I lost an electron", the other says "You sure?" then he says "yeah, I'm positive".


I'm smart.

Astrophysical questions?

I always wanted to know why groups of astronomical bodies always contract into relative plates, like the Milky Way and our Solar System.

Oh, just in general.

Also is it possible to send vibrations through a planetary body and study the returning vibes to understand the geophysical makeup of it from orbit, as opposed to on the ground like we do now.

Can you remotely measure sentience in beings? Like from outside a Solar system? Do humans actually emit "brain waves" unlike other animals or is it just pure science fiction?

sorry man not in the astrophysics realm...yet, only earth physics.

Why did the chicken cross the Mobius strip?

To get to the same side.

Bonus if you understand that joke.



I love astrophysics and astrochemistry. Hate xenobiology and astrobiology though. Heck, even regular biology.

BTW. Xenobiology includes astro, but not the other way around. This is why I may seem redundant. Covering all my bases.

It's all good.

Heeheehee, I got bonus points.

There is this farmer who is having problems with his chickens. All of the sudden, they are all getting very sick and he doesn't know what is wrong with them. After trying all conventional means, he calls a biologist, a chemist, and a physicist to see if they can figure out what is wrong. So the biologist looks at the chickens, examines them a bit, and says he has no clue what could be wrong with them. Then the chemist takes some tests and makes some measurements, but he can't come to any conclusions either. So the physicist tries. He stands there and looks at the chickens for a long time without touching them or anything. Then all of the sudden he starts scribbling away in a notebook. Finally, after several gruesome calculations, he exclaims, 'I've got it! But it only works for spherical chickens in a vacuum.'

Honor me!

A lawyer, an accountant and a physicist are discussing, over a beer, whether life is better with a wife or with a girlfriend.
"A wife is better," declares the lawyer, "because of the family support and the help she'll be to your career."
"Nonsense," says the accountant. "A girlfriend is better: you can keep your independence and go out with your friends more."
They turn to the physicist, who says, "It's better to have both. That way, the wife thinks you're with the girlfriend, the girlfriend thinks you're with the wife, and meanwhile you can be down at the lab!"


hehehehehehehe .......... I'll stop now.

You keep telling yourself that.

In the UK, that question would only be found in Mechanics (Physics for mathematicians). We don't do anything about the co-efficient of friction. Luckily I did Mechanics, so I'll solve it later.
Anyway, if you're a Physics genius, then have a go at this Physics paper. Just so you know, you need about 50% for an A.
The answers are here, but don't look at them until you've finished.

EDIT: The answer's 0.23, assuming that the maximum friction has been reached.
