Can /sci/ solve it?

It's just the back seat, isn't it?

The friction is the fucking product of mass and coefficient if it's on the horizontal plane. Even if it's not, assuming it's on the same plane, it would still be proportional. You know how to do a product, genius? And you know how to compare two real numbers? Great, so do it.

0.7*40 = 28 (back seat)
0.5*(40+10) = 25 (front seat w/books)

she should sit in the back seat.

Just use

F = u*m*a[d]*BroSine(?)

All you need is compare u1*m1 to u2*(m1+m2), since everything else is equal.

FYI, you can copy an image of your screen to clipboard by pressing 'Prt Sc' in the upper, upper right of your keyboard. Copying and pasting it into MS Paint then allows you to save it.

The fact that what fizx said was obvious, was itself obvious to all but OP. Thus I'm wondering if I could have started an infinite recursion by attaching a Captain Obvious to this post, pointing at yours.

Just because it is learned early in one's life doesn't mean people are born knowing it. The OP didn't seem to know. Or do you suggest we simply mock everyone that doesn't know everything we know?

Had I been off the ball this morning, that post probably would have blown my mind.

these clickers are ruining education. asking simple problems that 99% of most math/science anons can answer in their heads leads to classrooms full of moronic dolts that feel they need to ask an image board for help with their hurr durr "interactive" quiz

tl;dr america is losing the math/sci game, and this shit ain't helping

Yeah, there is clearly a "Less-obvious-then-the-previous-one" coefficient somewhere. If it doesn't depend on n, then we get an exponentially decreasing obviousness with time, so we know at some point we'll be less obvious than the captain-obvious threshold.

However, I would believe that once you've noticed that if it was obvious, then it was obvious that it was obvious, which was itself obvious, well, people probably infer very fast that this will go on. It is easier to understand that obvious^10 => obvious^11 than to understand that obvious => obvious^2.

So the coefficient is probably increasing and goes to 1 when n goes to infinity. And now we're stuck until we have its exact expression, as the convergence <span class="math">\displaystyle\prod_{n=1}^{\infty}c_n=\prod_{n=1}^{\infty}(1-\epsilon_n)[/spoiler] depends on how fast <span class="math">\epsilon_n[/spoiler] tends to 0.
