For question 3 I got the tension was 118 N and the reaction from the wall was 24.3 N and for question 8 I got that force X was 81.4 N. For question 7 I remember using trigonometry to get an angle and then taking moments about A to find the reaction at C and then to find the reaction at A you took the weight of the ladder and you took it away from the vertical component of the reaction at C. I don't remember what I got for this question and the two trains definitely met at 400s. Can someone confirm if my methods or answers are correct
I did exactly the same as you and got the same answers.

I know where I went wrong in question 4. I accidently wrote down 260s=4minutes instead of 160s. Too late now. I can't believe I did so badly...
You really don't know how devastated I am right now.
I took the reaction at the wall to be perpendicular to the ladder because it was placed at the corner the reaction would have both be pushing the ladder to the left and up. Then resolved the weight of the ladder it was parallel to the reaction. I may have resolved incorrectly... Then the sum of the force facing up and down would have been equal to 0 as they were in equilibrium. I know my value for X is wrong because I forgot how to deal with objects accelerating on an inclined plain.
I'm doomed

But 4 minutes equals 240s
4. I got the same answers as those, I have my question paper home with me if anyone wants me to take a picture of any of the questions so they can double check what they got to see if it's right

Could you that would be great.

Silly me. I 'm not even thinking straight. I'm very annoyed with myself and I have a cold and I'm about to start crying.
7. Hopefully the grade boundaries will drop, I completely messed up the last question too because I didn't take X to be horizontal and I put it it parallel to the plane, this means I won't even get diagram marks, so so annoyed
8. Does anyone know what the raw mark grade boundaries for the m1 exams usually are. Would 60 out of 75 be an A

I need a B in Maths to get into uni. I'm sitting on a C at AS (I got Cs in M1 and C1, D in C2, and a U in S1 - I am repeating them all (I did no work last year because I think I had a form of depression)). I'm in a better place mentally now and I really want to do well and I know I'm good at maths, today was just a bad day. I can't help but panic now though.

If you don't mind me asking what was your raw marks for all those modules to get those grades. It should say on the results statement sheet.

I'll have to find it when I get home
12. what was the size of the force holding the ball in place in number 3?

what was the size of the force holding the ball in place in number 3?
I got 118 N for the tension and 24.3 N for the reaction
14. (Original post by Golden hawk)
I got 119 N for the tension and 24.3 N for the reaction
what was the question again? I'm trying to remember the diagram?

what was the question again? I'm trying to remember the diagram?
The diagram showed a 40 N force pushing a ball of mass 10 kg against the wall at an angle of 30 degrees to the horizontal and the ball is held in equilibrium by a light inextensible string at an angle of 5 degrees to the wall
16. thankyouuu! i got the same answers as you! does anyone have answers for number 6?
18. Overall what did everyone think of the difficulty of the paper, I thought it was quite easy apart form question 6
19. (Original post by caoimheb100)
Yeah I got those as well! What did everyone get for the total distance travelled, i think i got 24.9
Same
20. Could someone please upload the question paper!!! It would be very useful, think I messed up big time
