well that's exactly what I thought and did, but the majority of everyone here has done it the other way so I'm assuming we are definitely wrong. We probably both misread or misunderstood the question? It can happen.(Original post by youreanutter)
yeah the question definetly sed
what was the force exerted
on the scale pan
by the brick
so do u not find the force on the scale pan the normal reaction of the scale pan as i doubt it wud be the other way around as if so it wud basically bethe exact same as the 2015 paper again
Anyway we would only lose one mark for doing what we did based on the Gold 5 Paper.

if you took moments about A and B you would get 2 unknowns which is why they state its on the point of tipping. They expect you to know that so I don't think you would get the method marks for creating an equation around those points.
If you found out the correct answer, they would give you the marks as your method must have been correct to give you that.

Oh okay. So lost 7 marks for that question then. For question 8, i did 2T^2 to get the resultant force and I got the same answer. Would i get atleast 2 marks for that.
also you could have gotten some of the latter method marks in question 7, examiners can be quite forgiving.

For q4 i stupidly got 32.5 instead of 40 and carried that forward could anyone tell me how many marks i've potentially lost

These are my answers:
1(a) 104, (90+14)
1(b) p = (400+15t)i + (20t)j
q = (20t)i + (8005t)j
1(c) The 'j' vectors for both are equal, as it is due west.
8005t = 20t
t = 32
therefore q = 640i + 640j
2(a) T = 20.6N
2(b) 15.45 N => 15.5 N (3sf)
3(a) Acceleration = g/8
velocity after rebound = 3.5
thus Impulse = 3 Ns
4(a)
4(b) Area under graph = 975
Area for slower car for first 25 seconds = 750
975750 = 225
1/2 * b * 30 =225
b = 15
total time = 15+25 = 40
so area under faster car = 975 = 1/2 * (40)(T+40)
T = 8.75 s
5) μ = 0.73
6) For 1st situation, R(T) = 0
For 2nd situation, R(S) = 0
M(S) => 0.5M = 30d15
M(T) => M = 60  15d
Therefore,
d = 1.2m
M = 42kg
7(a) F2 = 2.5i + 2.5j (this required simultaneous equations)
(b) V = 12i +5j, thus speed = 13 ms1
8(a) Fmax = 0.3g
acceleration = 0.6g
Tension = 11.76N = 11.8 N (3sf)
8(b) RF = √(11.76)^2 + (11.76)^2 = 16.6
It has a bearing of 225

I wrote the symbol X instead of lambda for question 7a, would I lose marks, I got everything else right including the answer.
Also, for question 3, when doing F=ma, I didn't calculate or include friction in my equation but did everything else, how many marks would I get? Cheers

if you got the correct magnitude of tension i think you would get 3 out of 4 marks, the final mark comes from stating the direction.
also you could have gotten some of the latter method marks in question 7, examiners can be quite forgiving.

Thank you. Do you know how the marks for the moment question will be broken down?
1 mark for eqn of mom s
1 mark for eqn of mom t
1 mark for solving together
1 mark for d
1 mark for subbing d into m
1 mark for answer
and another mark in the second part somewhere here
this is what i think based on past questions anyway

im not sure how question 3 marks would be broken down, but if i were to guess then
1 mark for finding acceleration
1 mark for finding final velocity
1 mark for calculating impulse
1 mark for final answer
1 mark for magnitude
maybe some A1 marks sprinkled in there somewhere
its a difficult question to say as its the first of its kind, i thought that question should have been worth maybe 8 or 9 marks compared to the other questions that were easier and had more marks

its more skewed as well if you get high or low marks

not a clue, personally I would say 64 for an A, others have been claiming lower, but I think that would be wishful thinking.

ALL ANSWERS HAVE BEEN EXPLAINED  CLICK ON THE MODEL ANSWERS TAB!
IMPORTANT NOTE: After speaking with some maths teachers, they have said that they believe the grade boundaries will be relatively low due to the simultaneous vector question and question three!
*So people stop asking, when using 'g' 2 or 3 significant figures is fine.
How many marks should I give myself?Spoiler:Question 1: (10 marks)ShowWhen using an approximation such as 'g', your answers should be to three or two significant figures or you lose one 'A1' mark.
Generally, every equation you form is worth a mark (that doesn't mean you can write random equations and get marks, they have to be part of the steps to get the answer)
If you got your final answer wrong, either post in the comments how many marks you think you should get, or look up previous questions that are similar by googling 'edexecel m1 questions by topic', choosing your topic and then press CTRL + F to find a question with similar marks. Look at how the marks have been distributed and compare it to the question.
Finally, mark it twice first harshly and secondly generously so you give yourself a range of possible marks, for example 5963 marks earned.Spoiler:Question 2: (6 marks)Show1(a) 104, (3 marks)
1(b) p = (400+15t)i + (20t)j (3 marks)
