For question 34b, why do they give us the potential energy? I just subtracted total by potential. How much marks do you think they will give me?

Retarded trick question

I did the same, I’m sayin 2

Hey guys. Does anyone have the solution to the last question of 2023 HSC physics? Thanks

I put one in post #444

 

[tywebb]

And here is another solution. This one also includes solutions to the q33 and 34

 

[tywebb]

It's a bit hard to read isn't it. So here is a latexed version of the q33 and 34 from this one.

 

[tywebb]

so now joining it to eddie's we have a latexed version for the whole paper

 

[tywebb]

I reproduced in latex the calculations for q34 faithfully to the handwritten one - regardless of mistakes and/or skipped steps.

I checked them with a calculator with values of G and M_E as presented in the HSC exam data sheet and they seem to be correct.

But do you think it could be improved with more steps showing substitution of values?

Happy to do that later if you think it necessary.

Also if you use more accurate values of G and M_E you actually get different answers.

and now this mg from nesa: https://educationstandards.nsw.edu....-f8f0c52a-4329-4b8b-b330-4a9ea336d452-oLRjsR6

matrix solution wrong for Q28 (they forgot to add the vertical displacement found in part b

lol im looking at the wrong thread mb.. but the 2024 solution for q28 on matrix website is wrong
