<p>Mech. energy is conserved because kinetic energy goes UP and grav. stays the same. </p>
<p>Kinetic energy is greater WHILE ITS MOVING vs. while it is stationary.</p>
<p>I believe 4 root 10 was B.</p>
<p>Im not positive but im leaning towards 4 root 10 being B ..i remember it was near the top of the answer choices because i read the bottom first and 6 root 10 was liek C or D</p>
<p>anyone know if there was an answer choice of 6 root 10?</p>
<p>what did the graph on the first question of the last science passage look like?</p>
<p>Just remembered.......the math problem where we were given 5 graphs and the question asked '' if the ball is thrown up at a constant speed and then drops'' which graph demonstrates best?</p>
<p>I remember putting the graph where the curve goes up but then goes down, not in a curve, but straight down</p>
<p>i chose the graph that curves up and curves down still going down the x axis..i think because the 2 axises were time and height or something so as the ball is falling the time is still increasing or something</p>
<p>it might have been that the question said after the ball hit the wall it bounced back to the ground....which is saying that the ball didnt fall straight down but it kinda boucned back off the wall towards the person like it would if u would throw a ball at a wall</p>
<p>oh because i remember my math teacher telling me that when the ball goes up the speed is the same as when it comes back down? I don't know i mightve heard wrong or something</p>
<p>well actually i think u can throw the ball up as fast as u want but the speed the ball falls back down with is gravity which is 9.8 m/s</p>
<p>what were the two variables...like the x axis was time or something and the y axis was height right? it mightve been something diferent but i focused on that question so i think i got it right</p>
<p>yeah true so the answer was the curve is slightly curved to the right going upwards but is curved more to the right when coming down>?</p>
<p>yeah thats the answer i picked...i was confident at the time but now since i dont really remember the exact question i cant rethink it</p>
<p>the one about the ice cream and the salt, heat is conducted from something to something else.. anyone remember the answer choices...</p>
<p>i think i picked something along the line of heat moving from ice cream to the salt, but then there was a part about a motor or stirring rod... if anyone can remember and help out here it'd be helpful</p>
<p>ryan you failed stop trying... j/k...</p>
<p>you said you were a good predictor of your score. What do you think you got</p>
<p>i remember putting the metal barrel conducted heat from the icecream to the ice salt mixture, as on the temp chart ice cream went down and the icesalt temp went up. and the only thing that can conduct heat is the metallllll barrel.</p>
<p>and the graph one was the bell curve, as the other choices had you going back in time, or the one with line straight down had time stop. it was the only plausible answer choice</p>
<p>Wait, was there an answer choice that specifically stated that the KE will go down as the GPE stays constant in the last question of the science test??? All I remember is that there was only one answer choice where the KE changed and I marked that and I'm pretty sure it went down since they were asking how it was affected when the block stopped mocing as it went up the incline plane.</p>
<p>Did anyone else think that firewood question in the math section was a typo? The number of hickory firewood (25 bundles) was a given, yet it asked you to find # of HF, and 25 wasn't a choice. I don't think i misread this.</p>
<p>it asked for the number of pine which was 17 i think...</p>
<p>The one about the gravitational potential energy at the top of the plane was that it was equal to the total mechanical energy because of the law of conservation. Also the surface didnt have any friction so no mechanical energy was lost on it.</p>
<p>9 more days until we can see our scores......for a fee though :(</p>

<p>There was an answer choice that said KE goes up while GPE stays constant and another choice that said KE goes down while GPE stays constant.</p>
