Auxiliary Angle method I think. I did do that, here's my working (I apologise for the messy work lol): I got 3/4 marks (which isn't bad), so I lost one mark as there's supposed to be two solutions instead of one.

Hey guys, can someone please do this question and provide a solution to this question? (please provide working)

Thank you so much! I was confused on how to present such info when answering a projectile motion question and this has helped a lot :)

So, when integrating from acceleration to velocity (ie. x double dot and y double dot to x dot and y dot respectively), we substitute c with the initial horizontal and vertical velocities. Do we need to write "Initial conditions" to explain why c is the initial velocities or is it not required?

Hey guys, How would you derive the cartesian equation for projectile motion from the horizontal and vertical accelerations of the object? In other words, How would you derive the cartesian equation from this step: x double dot = 0 & y double dot = -g (assuming that upwards is positive)

Yeah, I'm not too sure if it's required to know it - but I've just memorised the CNO cycle, p-p chain and Triple Alpha process just in case. I've never seen a question where they ask to write the reactions in any of the practice papers I've done so far, but it should still be considered as...

Thank you everyone, I realised that I had interpreted the question incorrectly. My calculations and reasoning was answering this question: What time does it take to cover the same distance at perihelion as during one second at aphelion? Once I read the question again, I began to understand...

Yes, it is

I was practicing mod 5 (advanced mechanics), and I stumbled across this question: I put A - as it's just logical to think that as per Kepler's second law, an orbiting object covers the same area of space in the same amount of time no matter where it is in its orbit. Hence, if an object is in...

I'm getting low 70s raw mark atm for past hsc physics exams (with replacement questions). Idk if there's enough time to suddenly just improve and get 80s raw for physics though.

Hey guys, I've recently got the "Success-One HSC Physics 2021 edition" and "Success-One HSC Chemistry 2021 edition". These two books have some past HSC papers with replacement questions. I've done a few papers for both subjects, and have been in a complete chaotic stressful state as I don't...

Hey guys, I am curious to get some knowledge on the engineering courses in UNSW and UTS. I've heard good things about both universities in terms of engineering accomplishments. I personally have UNSW as my first UAC option, however I'm also considering UTS as a worthy back-up in case I don't...

Ahh right, yeah makes sense - I had the idea that my chem mark would be around 83 and physics to be 88 or 89. So, that would mean that for physics - if I were to get a band 6, I would be aiming for approximately a 78+ raw mark - correct?

Oh right, thank you. Makes more sense now, so - the aligned marks are the marks you would see on your text message of the results after your HSC? And so, if I wanted to estimate my ATAR after receiving the text message with my aligned results (assuming that the HSC result I received via text...

Correct me if I'm wrong, but I'm pretty sure E2 is 50 - 68? So, I'm just curious as to why you've said that it's squarely in the 60s as it might potentially be in the 50s too. If it is squarely in the 60s, that would be good lol.

ok, thank you for your help!

oh right, ok thank you - and so I'm presuming that it is accurate right?

Hey everyone, I was just wondering what a raw mark of 50% in 'english advanced' would be aligned to?

Hey guys, I was curious on what a 65% raw mark in chem and a 75% raw mark in physics would be aligned to?

Hey everyone, I was wondering what a 45% raw mark in maths ext 2 is (very bad) and a 75% raw mark in maths ext 1 would roughly get aligned to?
