Everyone said it was easy, but I think I did so bad. Left the whole last question blank as I didnt understand what i had to do. already lost 23 marks. Wished I picekd another subject. Want to cry rn, but no tears are coming.

Everything went well till the last question😥. I had no idea as I got a curve and they ask for gradient.

I wouldn't worry too much Pabloscopy. Coming out of the exam it seems many were stumped with that final question, I'd say only the upper level students will get it.

I found most of the exam pretty typical for a physics exam. Maybe some of the multiple choice were slightly harder, and that final question with the graph probably threw people because there were two springs, rather than the typical one spring setup. A few very predictable linear acceleration/projectile questions. They used particle collisions to assess momentum conservation rather than vehicles, a nice question from an algebraic position (cancelling out the mass of the particles). No real tension questions. The loop vehicle question unexpectedly didn't assess minimum velocity but instead gave velocity at the top of the loop, making it an energy question. Relativity was pretty minor in this exam, I can only really recall a length dilation in multiple choice. Usual electricity transmission question, though perhaps a slight increase on comprehension and reasoning versus calculations.

For the last multiple choice question, did you choose the option where it said initial momentum is absorbed

Do you think I'm able to get 35< raw supposing im in the top 25% of my cohort? I guess I thought it was hard because it was quite different to previous years exams, including NHT imo, so I got caught by surprise. I have never seen a question like the last one, so got really panicked when I saw it and couldn't think clearly. This year's NHT exam was way easier imo, and got really high, so I guess I got caught offguard as I thought the exam would be of similar difficulty. Now I just can stop feeling disappointed of myself. Hard to forget about it

Yes you can. Please don’t stress

[Pabloscopy]

I chose that one, so I hope it's right

[Pabloscopy]

Yes you can. Please don’t stress

I wished I could, but I'm stressing even more now because I entered thinking I would do well, and be able to get really high based on my trial exam.

I picked that kinetic energy is absorbed

[memematt]

I picked that kinetic energy is absorbed

Yeah its KE - Anyone got solutions?

[Ryan_DS]

What K values did people get? I got 150 for 'a' and 350 for 'b'. Everyone I've asked so far have had different answers.

Thats what I got so hopefully others are wrong 

Edit: Actually I think I got 15, 35 oops

How is it kinetic energy? During a crash, you try to decrease impact force which aims to increase time. Since this is related to impulse(which is change in momentum), I picked momentum should be absorbed.

Yeh I got those too!
Just using the gradients
