Usapho 2014

<p>@Kaepernick if you have taken the paper test ask your teacher on Monday for your scores. If you took it on webassign you can go now and check your scores. The list of semifinalists is realeased at an undetermined time so nobody knows… </p>

<p>What if I need it for a summer program that’s due Sun. night and doesn’t allow for updates? Gah out of luck</p>

<p>good luck with simr kaepernick</p>

<p>You’re too good</p>

<p>no rly, I’m applying too :stuck_out_tongue: submitted app last week, the “no updates” emailed confirmed it haha</p>

<p>@mapletree7 how am I a ■■■■■. You can’t just assert something and claim it’s true like tbradsworth did. I honestly am trying to be diplomatic here, but you are pushing my buttons.</p>

<p>ok um can we all just stop arguing cus it’s sort of pointless
and actually talk about the usapho</p>

<p>anyway, anyone else remember any big problems from the test?</p>

<p>I remember an astronaut; I think that was momentum.
Also there was one with a spring cut in half</p>

<p>

</p>

<p>Did we not already establish this after reading the second post on page 9 of this thread :stuck_out_tongue: ?</p>

<p>(haha, no offense intended)</p>

<p>mapletree, pls :smiley:
what’s the spring cut in half though rly</p>

<p>If you’re talking about this problem “An object of mass
M
is hung on a vertical spring of spring constant
k
and is set into vertical oscillations. The period of this oscillation is
T0.
The spring is then cut in half and the same mass is attached and the system is set up to oscillate on a frictionless inclined plane making an angle
θ
to the horizontal. Determine the period of the oscillations on the inclined plane in terms of
T0.”</p>

<p>its T0/sqrt(2) this is because T~sqrt(m/k) and we doubled k by halving the spring. </p>

<p>oh and i should mention the period of a spring is independent of the orientation that it is in</p>

<p>Where are you getting the exact wording? What problem number is this?
Wish I could view the test…</p>

<p>@mapletree7 you do realize I made camp last year and almost made IPHO. My friends told me I was probably around 7th or 8th best physics student there. With the senior class graduating last year, I know that I will most likely make camp and probably IPHO.</p>

<p>@tbrad where are you!!</p>

<p>@tbrad we all miss you!!! come back!!!</p>

<p>well, sciencechamp, maybe you’re great at physics, and kudos to you, but honestly you sounded like a ■■■■■, or otherwise as if you wanted to stuff that fact down our faces :s</p>

<p>anyway I’m pretty sure torus has the right wording b/c his response is copy/pasted from somewhere</p>

<p>Its pasted from my test and scores i received from webassign so yes they are the exact words.</p>

<p>@torusdonut
Mind telling me which number this problem is?
What was the wording of problems 18-20? Sorry I don’t know how many I did</p>
