<p>where?</p>
<p>ok so number 18… that was the pulley one… thoughts? i got 50…</p>
<p>uhh I just posted the link but I’m not sure it will go through… i’ll send it to you if you want it.</p>
<p>what do ropes dangling from helicopters look like</p>
<p>straight slanted line.</p>
<p>oops.
how do you know?
I put the one that looks like half of a U because the tension in each successive rope element as you go down gets smaller so wind affects it more</p>
<p>@gatsbydies well then you’re wrong.</p>
<p>Helicopter line is the 1/4th circle in the second quadrant.</p>
<p>@tbradsworth no, it’s the straight line.</p>
<p>
obviously that’s the right way to go about telling me why my solution is incorrect</p>
<p>@greenbat23: i got my results already and i got it right. you can experimentally confirm it with a string of thread as well.</p>
<p>@tbradsworth please elaborate your solution.</p>
<p>@grenbat23 I’m not entirely sure we’re allowed to discuss – I will come back and post in 5 hours if you still want it. But as I said, you can experimentally confirm it with a string of thread.</p>
<p>@tbradsworth i have experimentally confirmed a straight line with a thread.</p>
<p>Noooo. I was going to put a slanted line but I thought it was too obvious. That irks me–I had just finished watching a video of a helicopter put out forest fires with a bucket of water the day before and the rope was slanted, I should’ve remembered that! Haha. I probably didn’t qualify since I only signed up after a couple of friends in Physics C asked me to, but it was still pretty fun. If any STEM-inclined underclassmen are reading this, I would definitely recommend taking at least one of the olympiads junior year. Cool stuff.</p>
<p>Edit: If you guys want to watch this in action, look up “helicopter with rope” on youtube and click on the first result! </p>
<p>thank you @coriander for backing me up!!</p>
<p>@tbradsworth are you sure your answer is correct?</p>
<p>@greenbat23 unless you are doubting the AAPT itself, I’m pretty darn sure.</p>
<p>@tbradsworth, no i just doubt your credibility and perhaps you saw the answer wrong anyways. videos clearly show a straight line.</p>
<p>and unless you are doubting the universe itself, I’m pretty darn sure.</p>
