Weekly HSC Physics Marathon[NEW SYLLABUS]

Hi there this is probably the first thread I've ever created so I'm quite inexperienced at this, but here goes   :-\

I've noticed with the new syllabus being rolled out that students have been expressing how questions are tough, especially because they have no resources to study the harder calculation/mathematical type questions. This is why I've created this thread.

I aim in this thread to create a collection of HSC level calculation questions for the new syllabus, especially as there is a LOT more emphasis on the Mathematical aspect of it. I will post questions on here regularly so hopefully at least someone finds them useful. All these questions will be of HSC level, so anyone doing HSC should find them as good practice.

I wish all the best for student's who are and will be taking Physics in high school, and also hope that this thread provides some good questions for you to train your mind with.

Note: I will not be focusing on the essay questions.

You will also need an account to see the questions...

Question 1:

This one is quite easy. Make sure to set your working and equations out clearly.

Hi DrDusk, this is a great thread well done! I'm excited to start answering questions! ;D

For the first question is this projectile motion? ???

Thanks again for the thread!

Very much projectile motion!

A question using using a similar 'type' of approach has been asked in the HSC before, so if you can do this, you can do any question they can ask.

Would you use tan() and sub it in as: 100/100tan(45)?

Sorry, could you please elaborate? I don't understand what you mean

Question 2: This will be the final question for this week.

This is a multi-part step by step question that requires you to picture the scenario and deduce what is happening. This is a common exam type question that they love asking. If you look in the sample paper provided by NESA, you can see that they like to ask questions like this where you need to use a graph.

This is not a very easy question, you will need to think. Luckily though you would only get one of these types in the actual paper.

Question 2 still stands! This question appeared in my schools trial and ironically I was the only one who got full marks

Has anyone attempted it? If your stuck I can give hints before I post the solution.

Solution will be posted today

The answer to question 2!

If you haven't tried the question don't open this first.

Question 3:

This is a good question. You will need to think!

A very good question for the new syllabus!

Let me add just in case, you may make the assumption that the effect of gravity on the electron is negligible

Also typo. The time spent between the plates should be 2.6 times 10^{-9} in the 2nd last line!
