    Application of orbital velocity formula to find speed at which earth spins?

    The velocity at which the Earth spins is a measure of its angular velocity, not its linear velocity. We don't deal with angular velocity or momentum in HSC Physics.

    4U vs 3U

    that would be too much. you would either have to drop a subject or i wouldn't advise picking up 4U how good are you at 3U? 4U is great for your atar but in the same way it also takes time away from other subjects.

    4U vs 3U

    65-66/70 Depends if they take a mark off for last q probability: in one of the lines of working I wrote (1- r) instead of (1-r^2) for the limiting sum of the GP but that was only for one line. Got it out though. Think I made up for my poorer than expected 4U performance.

    4U vs 3U

    63/70 is 96 aligned.

    Using a 4U method called implicit differentiation for the relation rates q allowed you to get it out in all of about 15 seconds. Circle geo was a little tough, something I wouldnt be surprised of seeing seeing in the early parts of a 4U paper. Last prob q was a common type of 4U q, similar...

    how does one do better in 4U than 3U?

    E4 raw mark??

    i'd say it was of average difficulty thus e4 cutoff high 40s /70 :)

    E4 raw mark??

    they never jump by that much (last year was 47). if it was to be higher, i'd say 49 MAX

    E4 raw mark??

    in all honesty i don't think e4 cutoffs will move at all from last years. last year was 47/70 for reference.

    i think for Q4, if you leave out the absolute value signs in tan(theta) = |m1-m2| / 1+ m1m2 | then you get the wrong answer lol

    product of roots is -d/a thus = -42.

    Section I: Multiple Choice

    C. use distance formula on both and set them equal. you get it out with some mild algebra bashing

    exact same as mine. i think these are the correct ones fellas

    OMG I DID THAT but for some reason it didn't work i always confuse myself with the expression of the last term so i guess i got 1 mark for that at least LOL. still happy.

    Did you get out rhe last q :) ? Its a pretty common 4U q I believe so yeah defs skewed toward 4U students BUT I still didn't get it lol goes to show how dumb I am
