Can anyone help!!!

For 8C I got the retardation right, however I misread the question, worked out the time between the string snapped off and the object came to a stop instead of the distance....how many marks do you guys think I'd lose?

Thanks guys!!

Please help me someone! I got every question right up to 8 where I stupidly put 36cos60 and 36sin60 instead of having the angle of 30 on each. I had a stupid moment where I added the two 30s together thinking I was resolving horizontally or something, this obviously gave me the wrong answers to all of question 8, do I lose all 14 marks or do I gain any as all the working is correct I just got that angle wrong? Please someone reply that actually knows what they are on about

It wasn't a difficult paper but the thing that I found challenging was just how little time I had left. Usually I have at least 20 minutes to check my answers but I found myself finishing with only five minutes to go. The last parts of 5, 7 and 8 were all quite challenging. Hopefully with 63 I can scrape an A. Although 69 is way too high.

Take the last 5 marker out and the paper was very student friendly.
Not a good paper to differentiate between top students IMO.

I had about 10-15 minutes checking time, but I check as I do it. This means I don't have to re-read the question and understand it again at the end. Its a lot more efficient if you are confident you will have enough time to finish the paper.

no, the question implies the particle continues to move up the plane until it comes to rest.

i always mastered such questions when i did the past papers. i knew due to inertia the body would continue to go up. this HAD to happen in the main paper. SO highly disappointed!

Just a quick question. With the graphs I labelled the time axis like this <----6----> as apposed to marking the time at a certain point along the graph. Would this be acceptable?

Cheers!

For the moments question (part b), does it matter if I multiplied by answer by 9.8 at the end and got rid of the g?
