ben322 Posted November 15, 2014 Report Share Posted November 15, 2014 what did everyone write for Q7b on paper 2? it was the one about "why does the graph pass through point A again"'twas a tough one i felt - totally had no idea how to tackle this as it hadn't appeared in the past year papers ... Anyhow, I mentioned how the negative area under the curve = negative displacement and since the particle travels on a straight line, it means that the particle definitely moved past its origin. :/ Reply Link to post Share on other sites More sharing options...
KamiKara Posted November 17, 2014 Report Share Posted November 17, 2014 I actually thought that both papers were actually pretty reasonable compared to some past papers, the last question on paper 1 definitely was hard though! What did everyone get for their answer to the last part of it?Square root 2 (I wrote 4th root of 4, which is the same thing because stupid exponential laws) Reply Link to post Share on other sites More sharing options...
trisprior Posted November 17, 2014 Report Share Posted November 17, 2014 Damn! That's what most people I've talked to got... I somehow ended up getting 2 haha Reply Link to post Share on other sites More sharing options...
ben322 Posted November 17, 2014 Report Share Posted November 17, 2014 Damn! That's what most people I've talked to got... I somehow ended up getting 2 haharoot 2 is right. i got 2 too though - extremely careless algebraic manipulation and for some reason i think you committed the same algebraic SIN too! :/ 1 Reply Link to post Share on other sites More sharing options...
trisprior Posted November 17, 2014 Report Share Posted November 17, 2014 Argh! Serious? Damn hahaha, eh that's okay, we tried! haha Reply Link to post Share on other sites More sharing options...
eliflora2412 Posted November 18, 2014 Report Share Posted November 18, 2014 I found the second paper more difficult than the first one. I didn't finished the excercise 10! Reply Link to post Share on other sites More sharing options...
eliflora2412 Posted November 18, 2014 Report Share Posted November 18, 2014 I found it.. okay. There weren't any questions I could not do so it was great. Probably made some errors. What'd you all get for the volume of revolution question in paper 2? f(x) I drew had y intercept at -1 and x intercept at ~0.7 I think.The volume I got was wrong I'm pretty sure because I think I forgot to multiply by Pi. It was <1 if I remember correctly.I got a volume of something like 0.68 or something around that because I forgot to square the function so got that wrong haha. I think from memory it should have been 30 or something because it was meant to be modulus as the function went negative (if this is the question where the function was above and below the x axis?). ****! I made the same mistake as you! Oh, whatever. I think I pass though! Reply Link to post Share on other sites More sharing options...
