<p>oh right, guess i mixed up mass and weight in my reasoning…</p>
<p>in BOTH cases the mass is offset by the buoyant force. ignore tension for this part of the problem, it is an internal force. its just that in the second scenario, the volume formerly displaced by the anchor is now displace by more of the boat, because it sinks.</p>
<p>I thought for the bouyant/anchor problem I thought the anchor was just pulled up…not pulled fully onto the boat.</p>
<p>oh crud in that case d’ would equal d.
i read it as the anchor going onto the boat (so it is no longer submerged).
anyone know?</p>
<p>also for the wires one which side of wire Y had the greater electric potential?</p>
<p>Did anyone else have circular motion for the first frq??</p>
<p>which question was that?</p>
<p>Randomandweird i think i did. the car one?</p>
<p>@Term664
Yeah!
I think we had different forms than everyone else…</p>
<p>Can we communicate some other way besides this forums lol</p>
<p>@term664
i’d really rather not</p>
<p>I had the car one too! Form E?</p>
<p>@careful
YES!!!
I thought I was like the only one!
Everyone was talking about the anchor for Q1 and I was like What???</p>
<p>I had a car</p>
<p>I heard something about form e being “experimental” </p>
<p>I just don’t know</p>
<p>How were you supposed to find the spring constant?
I just wrote down a bogus value and used it for the next subquestions.</p>
<p>.5mv^2=.5kx^2</p>
<p>find K</p>
<p>how do you guys think this was compared to sat 2</p>
<p>I have couple questions
- how did you guys draw the graph of KE and acceleration?
- the volume goes down, the pressure stays the same, and the internal energy increases, right?
- how did guys solve # 6
- do you guys remember question 1/2?(like the exact numbers?)</p>
<p>ke is concave down parabola. A was upside down V
I said that v goes down p goes up and so does T.
question1: Buoyancy 61.25N tension 428.75N
Question 2 V=4 m/s K=1280, f=1.2 Hz</p>
<p>I don’t think KE is an upside down parabola because at x=0 KE is 0. Right?</p>
<p>why is KE concave down? Isn’t KE maximum when the spring is at its equilibrium?
and as far as i know, the spring potential energy is the greatest when it is either stretched or compressed to its maximum.</p>
<p>Do you remember numbers given in the question for # 1 and # 2?</p>
