Usapho 2014

<p>I got C on the paper version and I think that’s correct.</p>

<p>I understand that results will be posted Monday or Tuesday, but where will I be able to find them? AAPT website? Webassign?</p>

<p>I got like C or B or D on the paper version too.
But idk for the bounds on the speed ration in collisions problem (mass m and mass alpha * m) problem I remember getting like C or something on the paper version but I remember getting the right answer, and one of the people I know who also took the paper version is sure he put A for that problem… Huh…</p>

<p>I’d like to know this too! I think they’re already up on webassign, but hopefully the AAPT site will be updated by tomorrow or so. </p>

<p>Right now I’m just hoping that only some answer choices differed in order between WebAssign and paper.</p>

<p>jxt - on the alpha collision problem, I got B. I’m confident that’s correct as well. Just the bounds by the perfect elastic and inelastic collision.</p>

<p>moustache - They should be here (under the news section): <a href=“2014 U.S. Physics Team - Home”>http://www.aapt.org/physicsteam/2014/&lt;/a&gt;&lt;/p&gt;

<p>Coriander - I think the webassign folks have their scores, but they don’t know if they qualified because the cutoff has not been announced. When they post the list of qualifiers tomorrow, you won’t get your score. You will only know whether or not you qualified. Only your teacher can tell you what you got if you took the paper version.</p>

You mean B on the paper version you took, not on the online version uploaded here, right…? That makes sense.
As in,
(1-a)/(1+a) and 1/(1+a)</p>

<p>jxt - yup. That’s what I remember getting.</p>

<p>Nice, me too. I guess paper versions differ slightly from each other possibly for non-numerical questions.</p>

<p>jxt - I seriously doubt that the paper version differ from each other, otherwise it is a mess for grading. There wasn’t a “form a/b/c/etc…” bubble to fill out, so it would be impossible for AAPT to figure out which scantron corresponds to which test. They have to standardize the paper. The reason they could scramble the webassign is because everything is computerized and automatically graded.</p>

<p>Oh, yes, that is true. Wow, that was stupid of me to suggest the paper versions could differ.
I still find it awkward that someone I know took the paper version says he got A for that problem, though, and we got the same answer.</p>

<p>It’s possible that the two choices are similar enough to trick both of your memories :slight_smile: I’m pretty sure A on the paper version is not correct.</p>

<p>I hope that that is what happened lol.</p>

<p>Sorry for all this worrying about answer choices; it really scared me for a while today. I hope it’s just that our memories are not too great for things that happened over a month ago.</p>

<p>Oh, I completely understand your worries :slight_smile: I do exactly the same thing. I blocked all this out of my mind while preparing for the AMCs, but now that the B is just over and I made AIME, I started worrying about the F=ma again :slight_smile: ha ha</p>

<p>The exact same thing happened to me, with AMC and F=ma!</p>

<p>I’m a sophomore in AP Physics B, and next year I’ll be in AP Physics C.</p>

<p>What should I do to be in a position to go to USAPHO semi’s as a junior?</p>

<p>I think you can start by reviewing the mechanics sections of your textbook and doing the harder problems in there. I’d also get an AP Physics C book for the deeper conceptual content and review the mechanics there as well.
And you can also do past tests.</p>

<p>Would Giancoli 6th edition be usable?</p>

<p>I think it should be fine.</p>
