<p>@zkaplove17, my apologies if they were directed at you haha. I was speaking to the people who believed that the acceleration vector was straight down towards the sun (which is incorrect)</p>
<p>The comet was not directly over the sun. The orbit was elliptical and the sun was at the left focus. The sun can never be at the center of an elliptical orbit unless that orbit is also a circle (Keplar’s laws).</p>
<p>And you’re right with your answer; it was down to the left. Pointing at the sun. Same thing.</p>
<p>whatever it was, however the diagram looked, can we agree that v was tangential and a pointed towards the large M, (sun)…</p>
<p>and move on to a happier problem :)</p>
<p>the comet was not directly above, thus accelerating pointed southwest, velocity perfectly west</p>
<p>Sorry for bringing it up guys… :(</p>
<p>Regardless Andrew, it’s apparent we have reached consensus that acceleration was towards the bottom left. If that’s what you are arguing, than we actually have no disagreement.</p>
<p>Noooo I read the problem wrong and I thought the sun was directly underneath! GAH.</p>
<p>for a question that gave many properties of sound it was (D) frequency, i dont remember it so well other than that…, and did people put galileo?</p>
<p>^ I did that as well! For both.
I’m pretty sure I put Galileo, hopefully I didn’t change it.</p>
<p>Yes and yes. I think it was waves in general not sound. But yeah same whatever</p>
<p>I did only because I remember Newton doing something with planet orbits, and I knew Galileo had done something similar.</p>
<p>the first four were obvious, did u guys get -2 for the charge wasnt possible?</p>
<p>I put Galileo because everyone else I’m pretty sure was born after Newton died.</p>
<p>it was because Newtons laws of motion were predicated on Galileos laws of falling bodies</p>
<p>Yeah -2. And for the 1st part of that question, u, s, d? Also, if I remember correctly, Newton was born the day Galileo died.</p>
<p>Yes I’m pretty sure I got -2. What were the other options?</p>
<p>Yes got Galileo and -2</p>
<p>Yes, the answer was frequency because all periodic waves have it.
Galileo was born before Newton, so I put him as well.</p>
<p>Yes, it was u s and d.</p>
<p>What were the questions for the frequency and -2 answers?</p>
