1. Grade boundaries prediction. Im expecting around 64 since everyone found it eaay
2. (Original post by student bang)
To find the resultant force on the pulley do you do 2 tcos45
Yeah that's the one matey.

Did anyone else find the exam extremely hard compared to past papers? i couldnt do a single question.
I found Question 3 and 7 hard. Otherwise it was an average paper

How many marks was the impulse question worth?
Fairly sure it was 7 marks
5. Does anyone know the marks for each question ?
6. how many marks would i get if i put root 5 over 2 twice instead of 2.5i and 2.5j
7. For 8(b), the very last question, I'd have thought accompanied by a diagram specific to that part of the question that either 45 degrees or 135 degrees from the horizontal is valid. I'd have thought a bearing would also be valid too. It didn't specify how they wanted it to be given.

Can someone explain why I got 1.7N something for F2.

I am 100% my trigonometry was right so I used the sine rule to find F2 and I got 1.7 on one side. What did I have to do with this 1.7?????
I set up a pair of simultaneous equations:

F1+F2=R => ( - i + j ) + k( i + j ) = a( i + 3j ) I can't remember the vectors given exactly, this is what I think.

Then equate i components: -1 + k = a
Then equate j components: 1 + k = 3a and solve for k.
8. would i get the mark if i write the direction in 8)b) as South West?

Cheers absolute legends. How many marks for 0.2 you think?

Woops, didn't see the root5. You'd probably lose the accuracy marks - but as long as there is working, you should get some M marks.
11. How did people generally find this paper? Difficult? OK? Easy?

And how long does Arsey usually take to get the solutions up?

no it was ( root 5 over 2i and root 5 over 2 j)

Mate he got banned from doing it (
16. How did people get 3Ns for the Impulse??

I = mv - mu

I = (0.4)(4)-(0.4)(-4) = 3.2Ns

Idk

Arsey has stopped publishing his model answers unfortunately.
18. @Arsey , I know you're watching this thread, show up boy!!!

He's stopped posting unofficial mark schemes
20. I accidentally did one of the questions in pencil :/, marks or no?
