Maths Ext 2 Predictions/Thoughts (1 Viewer)

[notme123]

but those werent initial conditions for memory

ye when x = 0, v=8 and x=5.5 which wasnt really needed until part 2

thought you could only do definite integrals with intial conditions lol

oh ye you can do it whatever as long as the variables match

 

[tito981]

what do you guys thing 84 will scale to

just weird i made a displacement eq and when differentiated and rearranged it made the other eq

 

[Anaya R]

How did you guys do 16a?

 

[Jojofelyx]

what do you guys thing 84 will scale to

92

The second part of the slope question, i forgot the theory behind it, was it just when the forces acting upon the object = 0?

Would you guys say this year was harder or easier than 2016 HSC Ext 2

i mean the course content is completely different, theres no way the new syllabus content even comes close to the schite they did 2019 and prior lol

yeah believe a=0

god when i saw one question take up an entire page, that scared me. at least during reading time.

 

[JesusChriiii]

yeah thx, and pick the positive V value right?

ye ik the volumes question was such a waste of marks

thx to the dude who provided the copy of the paper. kinda thrown off by this m/c a bit. Ended up picking C in the end just felt like it looks like a regular projectile motion graph.....probs got it wrong tho, anyone got any ideas?

It's D. It can't be A or B as the particle will not continue along the path AB. It isn't C as the acceleration will result in a decreasing speed, whereas D has an increasing speed, as required.

Oh my god ahaha i changed my answer from d to c since i interpreted it as saying that the speed of the vector was increasing and it had to remain at constant speed in order for UCM to occur rip

i'm honestly super happy! i genuinely thought i was going to be at risk of getting under 30 raw because of how little i've studied due to low mental energy + moreso feeling really sick on saturday and sunday which is literally THE worst case scenario as a last minute crammer. for perspective, i got to looking at the vectors syllabus for the first time since trials at 11:30am this morning...

but i could actually do loads of the questions!!!! i think there's a good chance that i passed uni here i come
