<p>^definitely.</p>
<p>Allright, good.</p>
<p>ok im done with this test. Im going and wont be back till tonight.</p>
<p>If the answer was indeed 4 and 40 and the PE was stored in the string, then I’m hopefully still looking at a 36 for this section.</p>
<p>Consolidated list anyone?</p>
<p>it was stored in the ball.</p>
<p>@Joe</p>
<p>lol… PE was stored in the ball? Do you know what PE is? haha… >></p>
<p>Joe, I think you are mistaken. Have you taken a Physics course in high school?</p>
<p>I took ap phys last year… :/</p>
<p>lol. Sorry, but I am almost positive that the potential energy was stored in the string.</p>
<p>Potential energy can become kinetic energy. When the ball snaps towards the wall, the string isn’t where the kinetic energy in the system is coming from, its the ball.</p>
<p>The ball is being snapped toward the wall by the string. The potenial energy that is stored in the string becomes kinetic energy and that energy is used to snap the ball toward the wall.</p>
<p>‘and that energy is used to snap the ball toward the wall’</p>
<p>you have some kind of misunderstanding here. there is no kinetic energy ‘used’ to snap the ball toward the wall. kinetic energy is what the ball has as it speeds towards the wall.</p>
<p>I agree with NewAccount. If we were talking about dropping a ball from a skyscraper, then yes, the PE would be stored in the ball. But the ball is attached to an elastic string, and when such a string is extended, it has elastic potential energy.</p>
<p>It was stored in the string…</p>
<p>I put string as well.</p>
<p>It was the only one that made sense. It obviously wasn’t stored in the wall, the ball would only be if it was not connected by the string. Since the ball depended on the string, then that is where all the energy was stored-- right? Idk I don’t know much about physics but I do remember learning a little bit about it in AP chem</p>
<p>That was my reasoning as well</p>
<p>On a different note, since we have reached a concencus: I was so happy to see an osmotic pressure question. It was so easy, having taken AP Chem this past year.</p>
<p>Oh I know newaccount, I was at about 5 min left and I was sooooo relieved to see some chemistry. I didn’t even have to use the data lol. Molar mass of lactose and sucrose and van’t Hoff factor ftw.</p>
<p>^ Yessssssss. I just beasted those questions, if it wasnt for that chem section I don’t think I would have had enough time to finish.</p>
