Is this question ext 2 mechanics?

my teacher says it is and it shouldnt have been in the ext 1 exam, but just to get confirmation

I dont think so. This seems doable with 3u knowledge.

this is what my teacher said?

let me do this rq to see if its doable

Thanks man

I didnt even try it ngl, I aint never seen anything like it

Yes, I understand where your teacher is coming from. In "Mastering Math Textbook" there is mention of tension force but in the question, it explicitly says the net force on an object like M2 in this question is "Fnet=T-MG". But in this question, it doesn't so that's probably why your teacher thinks it is 4u. Ruse kids were mostly likely taught tension in their 3u classes that's why the writer of the paper did not know it was required to say the information regarding the net force. I don't know what it says in the syllabus regarding this, but if a question like this came up in the HSC, I am pretty sure they will mention that net force is balanced between T and weight force. (Image is from page 67 of Mastering Mathematics Extension 1)

Once you know that the net force is balanced by Tension and weight force, it is an easy question, utilise vectors to illustrate the different forces on m1 and m2.

I think its doable with E1 knowledge because the tension cancels out. So the equation is (m1+m2)a=(m1sin30g-T)-(m2g-T) and you solve for acceleration. Technically you could just ignore the tension all together

Seen this question in North Sydney girls trials 2024. I haven't seen anything like this before. What're the chances of this coming up tomorrow?

hmm seems a bit more 4u because of vector lines but i guess its technically doable. i would say unlikely though

u just gotta apply knowledge abt forces innit and it's in the mx1 syllabus too

how is that forces brev

thsc don't have 2024 ext. 1 trials yet. they are here: https:// community.boredofstudies.org/threads/2024-trials.410168/

Do you have any predictions for this years hsc? tywebb trial paper goat
