i think that p means the density of the medium the object is travelling through
if it did apply to the object itself, it would say F=ma=km where k is all the other formula stuff
cancelling out a = k? meaning acceleration due to drag is independant of mass?
i can't really draw the diagram here and i'm not sure if i even got it right but
it looks like you have to use the cosine rule to find the distance from point A
u end up getting: 100 = x^2 + 169 - (26cos20)x but this quadratic is messy
solving this quadratic u get x ~= 3.26, u will get 2...
i saw u in quanta then :haha:
i was in the 3rd row from the back, slightly right from the centre with a black jumper and glasses
yea the quanta lecturer was good, i was very suprised he actually did manage to cover the entire option in 3 hours, i thought Q2Q was supposed to be a harder option.
anyone notice that the guy who did space gave every question as a "maths-physics" question.
wtf, i thought everyone agreed that maths in physics is easy and that we should focus on the conceptual side to get ahead in marks
lol bos should have stuck to saying acceleration is ...etc, it would stop all the confusion and any 4u student should be able to apply newtons 2nd law(at least i hope so)
since ur treating k like it literally can be any constant:
if u mix it up between acceleration and retardation, can u still get full marks by having the same answer except k is a negative constant
not that i would try to mix it up, just incase.
lol at the justice game lecture
even the dux of my school resorted to drawing on the benches and in the workbook, cosmology guys may know him.
that teacher filled the entire notes section with activities, its more like a workbook than a resource book T.T
Re: Which subject is more "prestigious" - English Extension 2 or Mathematics Extensio
i don't do both so i may be wrong
i think that EX2 will require alot more work and effort than MX2 and to me, prestigousness is related to difficulty of the course as a prestigous course will be a "hard"...
u can sort of argue there is scaling, e.g u need about a 75% to get a 7 in Maths HL but need 90+ for mandarin ab initio
i did IB for half a year in year 11 and screwed up my language so i dropped, if i didn't have to do a language, i would still be happily doing it.
u have take a maths...
