Maths

[Baloki]

How would you go about solving the following maths problem:


Rebecca (m=40kg) is at the bus stop when her friends drive up. She can either sit in the front seat or the back seat. The front seat has a coefficient of static friction u=.5
The back seat has a coefficient of static friction u=.7. If she sits in the front seat she has to hold her friend's books (m=10kg). If she wants to maximize her total static friction force possible, which seat should she most likely take?

a) front seat but not the back seat
b) back seat but not the back seat
c) either the front seat or the back seat

And what would you say is your favourite aspect of the language of Mathematics? Did you do it at school and do you enjoy it?

I hate math :mad2:

That's more physics than mathematics.

Look you, I don't come into your threads ruining your thinly vied topics!

f = μN = μmg
for the front f = .5*50*9.81 = 245.25 N

for the back f = .7*40*9.81 = 274.68 N

The answer is she should sit in the back.

I love math. :bigsmile:

Math sucks.

I liked it enough to do a degree in it. But calculus, not stats. Stats is worse than <i>drama</i>.

I loved maths. Lots of fun. Working out a difficult equation is an awesomely fulfilling feeling xD And maths jokes are far funnier than most jokes, with the added bonus that most of the people around you don't get them.

9x-7i > 3(3x-7u) is a fun equation

Congratulations: You have just passed Statics 101.

Now, assuming that slipping is impending (coefficient of sliding friction = .3), write the equation of motion for the girl, assuming that the car has taken off with m = 1000kg, acceleration of .75g m/s^2
I'm not fucking doing it. Statics and dynamics were my least favorite parts of my degree

Oh man, I was the opposite. I loved stats and hated calc. Well, didn't hate... just never enjoyed. Stu and I cut out squares from our maths exercise books and created a chess set using them. Our teacher was unimpressed for the most part, but would generally be satisfied if we did our coursework on time despite playing chess at the same time. :D

Wait, Carny?

I saw this a while ago, I lol'd.

Calculus is better then Stats. Chances are you are either going to be tangent to the curve or just getting under the covers. :bigsmile:

Math jokes are always great.

The first day we started integrals in BC calc the teacher wrote on the board the integral of e to the x equals f of u times n. :bigsmile:

[fire_of_avalon]

I don't get it.

I don't get it.

Did you listen to the song while reading?

And yes, I enjoy mathematics. Enough to pursue a degree. I decided to grab a major in it at first because I liked Calculus, but I soon enough realized that Calculus is insufferably boring compared to other stuff out there. Give me Abstract Algebra over any type of Calculus and I will be a happy man (though I will admit that results such as Picard's Theorem are absolutely beautiful). I'll take Galois over Cauchy any day. :aimsmile:
