since hsc is close which r the best papers to do other than the past hsc ones
How many are you gonna do in three days just do HSCsince hsc is close which r the best papers to do other than the past hsc ones
all of themsince hsc is close which r the best papers to do other than the past hsc ones
harder papers? maybe cssa/independent?since hsc is close which r the best papers to do other than the past hsc ones
Does ngo not cover everything in the syllabus wtfomd i realised i haven't even learnt resisted projectile motion is it hard where do i learn it what do i need to know
WHAT THE FK IS THIS

what r these equations
ive never done a question like this before
If they don’t that’s genuinely concerning because I go thereDoes ngo not cover everything in the syllabus wtf
they haven't in some situationsDoes ngo not cover everything in the syllabus wtf
Oh wtf damn so what r u gonna do if they resisted motion thing comes upthey haven't in some situations
it just one small section of a topic it should be fine, the integration is horrific they better give like 10 marks just for deriving these equationsOh wtf damn so what r u gonna do if they resisted motion thing comes up
I feel like resisted motion isn’t really something you need to specifically understand you just need to know how to apply the mechanics formulas and then do some intense integrationit just one small section of a topic it should be fine, the integration is horrific they better give like 10 marks just for deriving these equations
ive never seen this in a trial paper either so idk it should be fine and its just mechanic-integration anyways so its not difficult
I'm just doing HSC I don't have time for others

anyone have any suggestions for 4u papers
there isn't much time so if u did a nice one lmk and we can share marks etc @SadCeliac @everyoneelsedoing4uinthestateorhasdonethenewsyllabus
Actually this model is not correct. If resistance applies to a projectile with a magnitude of , then the horizontal and vertical resistance can be correctly set as and if and only if n=1. You'll notice in Cambridge and the few HSC past papers where there is resisted projectile motion, it is always linear resistance. @tywebb wrote about this issue in NSM hereomd i realised i haven't even learnt resisted projectile motion is it hard where do i learn it what do i need to know

I think you might mean that is an inappropriate model for projectile motion, because without gravity the motion won't be projectile.Actually this model is not correct.

As a difficult question, try to prove by contradiction that if R is resistance acting on a projectile, expressed in terms of acceleration and not force (so no need to divide by m or whatever), then is an inappropriate model for projectile motion.
Yep, that's what I meant. Now who wants to give it a go?I think you might mean that is an inappropriate model for projectile motion, because without gravity the motion won't be projectile.

There is a whole thread on this at https://community.boredofstudies.or...rtional-to-the-square-of-the-velocity.388904/ the conclusion of which is that nsm and maths in focus treatment of it is utter rubbish.omd i realised i haven't even learnt resisted projectile motion is it hard where do i learn it what do i need to know

okay makes senseThere is a whole thread on this at https://community.boredofstudies.or...rtional-to-the-square-of-the-velocity.388904/ the conclusion of which is that nsm and maths in focus treatment of it is utter rubbish.
Furthermore the publishers and authors of those books were warned about this years ago and told to remove it from their books. They stubbornly refused to do so - the result of which is you and many other students have become confused and have become victims of their stubbornness.
If your school chooses to use nsm or maths in focus, then it will be incumbent on the teacher to explain why their treatment of it is inappropriate.
