Phase transition?

Gud's last question is actually simpler than it sounds. You still need to know the proper physics equation, or failing that, calculus, or you could realize that for this particular question there's a shortcut to doing the calculus.
I'm trying to remember how to do it! And failing. I think I'm right about it taking 4 seconds, though. And 1/2at gives me the right answer, but that could be coincidence.
Hold on a sec.
d = vt
That's for sure. Except v is an integral. Maybe you integrate both sides? Or something.
I don't believe in calculus.
It takes 2 seconds to accelerate to 40m/s. 40m/s = 10 * t^2.

From that you can figure the distance where d = vt + 1/2at^2
Is "They really liked you, but didn't think you were precisely right for that job, so they passed your resume on to another department." the interview equivalent of "Let's just be friends."?
Because I haven't had an interview response other than that so far. One position will let me re-interview for it, but not for a month or so. By which time I'd really like to be already employed.
Also, how does one correctly punctuate the first sentence?

Well, fuck a duck.

I don't remember anything.

You don't need that first comma.
All the whole "frictionless roller coaster" thing means is that the velocity can change direction without losing energy. And we can subtract the 1ms starting velocity from the ending velocity. So really, it's "how far does the roller coaster travel if it fell straight down, accelerated at 10m/s² and had a final velocity of 40m/s."
If the thingie traveled at a constant 40m/s for four seconds, it went 40m. But of course it was accelerating, so the distance would be less than that. Here's the trick: Because the acceleration is constant (eta: and the velocity started at 0), we can just divide the 40 in half.
