IBlicious Posted November 11, 2016 Report Share Posted November 11, 2016 How did you guys find physics Paper 1, Paper 2, and Paper 3? I did the engineering Option and found the question on the flywheel quite difficult because the question gave 2 radius' and I didn't know how to account for both of them. I'm not sure if I was the only one that didn't know what to do with the 2 radius' given. I tried adding and subtracting but nothing I did yielded the answer they were looking for. Paper 1 was my best and I finished it before time. I felt Paper 2 was quite manageable as well, and that it was easier than the May 2016 one. What do you guys think? 1 Reply Link to post Share on other sites More sharing options...
Maxxxxxxxx Posted November 11, 2016 Report Share Posted November 11, 2016 I found paper 1 pretty hard actually; paper 2 was comparable with the May one but I think the May one wasn't too hard. I did astro for paper 3 and it was doable, not really hard but really easy either. Hope that the boundary will be similar to the May one.

Fire-Explosion Posted November 11, 2016 Report Share Posted November 11, 2016 Paper 3 was heaven I did astrophysics as my option Paper 2 had too much questions to do, only made it to like halfway on question 10 Paper 1 was pretty ok Reply Link to post Share on other sites More sharing options...

Same I thought Paper 2 was comparable to the May one, and wasn't too bad. I was expecting something more difficult. What did you find hard about paper 1? I know many of my peers said that they ran out of time. I thought it wasn't too bad though. Reply Link to post Share on other sites More sharing options...
Fire-Explosion Posted November 11, 2016 Report Share Posted November 11, 2016 Paper 2 was not bad, it was just too much questions with less thinking time (via many 2 marks qns for the difficulty) Reply Link to post Share on other sites More sharing options...

I thought that the level of paper 1 was similar to the May paper, but I usually suck at paper 1 so... I think the first two questions frightened me a bit so I had that impression Reply Link to post Share on other sites More sharing options...
mack Posted November 15, 2016 Report Share Posted November 15, 2016 I found paper 3 (Engineering) much, much easier than both the specimen and May 2016's paper. There weren't as many calculations - the only Bernoulli question was an explanation.

I'm not sure if I was the only one that didn't know what to do with the 2 radius' given. I found it pretty straightforward - from the given values you could calculate an average acceleration for the falling object, which gives an average rotational acceleration for the flywheel + rod when dividing by the smaller radius since that's where the string is attached. Since Τ = Iα, you can calculate the torque. In hindsight, I think I used only I for the large flywheel, when it should have been the sum of both. I still ended up with ~0.3Nm as given though. For the tension part, you again use the small radius in Τ=Fr since again, that's where the string is connected. F equals the tension. In other news, paper 2 had nothing too crazy (difficult to even remember it now) although it may have been a bit long. Reply Link to post Share on other sites More sharing options...
IBlicious Posted November 16, 2016 Author Report Share Posted November 16, 2016 Thanks, I think I used the large radius throughout, my bad. I don't think I was thinking straight... Hopefully don't loose too many marks for that mistake! I thought all the other questions in Paper 3 went well. Reply Link to post Share on other sites More sharing options...
