If that is the 9 marker for tomorrow's paper, do you reckon the invigilators let me take a rope to the bathroom?

Where are you getting these questions from btw? They seem kinda weird

NESA sample questions for current syllabus. was given to teachers in 2019 as guideline for new content

How many hsc papers is too many for one day?

Real, studying is just doubting your ability

Oml sample answers in this booklet for teachers are so detailed
I've been giving myself full marks if my response in HSC past papers are better than samples but now it looks like im only on par if not below the standard
HSC sample responses are usually the laziest ever but obv the teachers get the actual detailed sample response cause why would the students need it?

What is the point of the sample answers in the hsc papers if they won't get full marks?

What the hell even is this question. Horizontal stays the same and vertical uniformly decreases due to gravity. Am I missing something?

horizontal is vector sum of car velocity and throw velocity
and yes vertical is correct

Even then, I don't understand why this is 4 marks. Like its horizontal is sum of car velocity and horizontal of throw and doesn't change and vertical is just from the throw and decreases due to gravity. I mean I'll take free marks for questions like this, it just doesn't make any sense for it to be worth this much.

Wait I just did this question and was wondering, is the horizontal velocity in the south direction only relative to the car? And if so do we say relative to the ground there's only horizontal velocity east? Or do we talk about both? Or am I just completely wrong?

The apple is already travelling north at the car's velocity. When it is thrown, some east velocity is added, giving a total horizontal velocity somewhere a bit east of north. These velocities should be relative to the stationary ground and there isn't any southern velocity, even relative to the car, as the apple has all of the car's velocity.

Yo do we need to know the fine details about the Zeeman and Stark affect?

Guys do I assume that air resistance is negligible for proj motion in this course (keep mixing it up with ext 1 and 2)

Yes bro

yes, only air resistance i can think of is in orbital decay

 

[v.tex]

no

lol I was full watching a uni lecture on this shit

yeah
