Will I get the mark for saying the direction of the force on the pully is Southwest??
i think you'll defo get the mark if you drew a diagram
2. how many marks was questions 8?
3. Can someone give me their opinions here...
How many marks will I lose on question 8.. i put the answer as 1.2N but forgot to times by g right at the end. i used this answer for 8b as well so will i get method marks? I got the angle right

8a 7 marks
8b 4 marks

Quite a few, I imagine you lose a 3+ for the part A but for part B i only see 2 marks max

8a 7 marks
8b 4 marks
you sure i remember 8a being 10 marks , because i got 8 completely wrong.

This was a resit for me, anyone else?
Which do you prefer M1 or M2
resitted this, and obs m1 becuase m2 hurts me in many ways

yeah cause all my working out was right.. and 1.2g = 11.76. hopefully I won't lose more than 3!!
10. How many marks was the moments question?

**** na I'm sure it wasn't that many... the only 10 marker was the coefficient of friction
8b was deffo 4 marks i remember that
12. Quick question hoping someone can clear this out1) for the first question I got got 14 soemthjng degrees and I mentioned this is from the positive X AXIS or to the right People seem to have done 90+ this to get from y axis but they didn't mention so I just used X axis 2) for the coefficient of friction I got the right answer but it came out negative because I took the friction pointing UP the slope and someone said it was down the slope How much would I lose out I think it was 10 marks ?
13. If I got 66 kg and the length to go with it would I loose many marks? Correct method

yes

With the first question it asked for the answer as a bearing which is why you needed to add 90.
As for the second question.. I'm not sure how many marks you'll lose maybe half?
16. how many marks do you reckon ill get?

1. a. 104 degree
b. p = (400+15t)i + (20t)jq = (20t)i + (800-5t)j
c. q = 640i + 640j

2. a. T = 20.6N
b. I put R=15.5N but put force on scale pan by brink = 14.7N - how many marks will i get?

3. Got everything write until the last line, so had I=mv-mu, and u=3.5, ended up doing a calc error, will that be costly?

4. a. Correct graph
b. T = 8.75 s

5. μ = 0.73

6. Found 2 equations using moments but couldn't go any further with it - how many method marks?

7. a. -1+k=z and 1+k=3z and sub z=-1+k into 1+k=3z so 1+k=3(-1+k) which gives k=0.5 so F2 = 0.5i + 0.5j - if this is wrong then how many marks?
b. V = 12i +5j, thus speed = 13 ms-1

8. a. Tension = 11.76 = 12N (2sf)
b. RF = √(11.76)^2 + (11.76)^2 = 16.6 = 17N (2sf) with a bearing of 045
17. (Original post by EpicTree)
yes
18. (Original post by Georgia.C123)
atleast 3
19. Grade boundary for this exam paper?

Is there another thread with a poll or something I can compare/contrast to last year?

100% = ?, A* = ?, A = ?, B = ?, C = ?
20. (Original post by Georgia.C123)
I did the same thing.. do you remember how many it was out of ? I think it was 7, I'm saying probably 4 marks we'd lose which is annoying cause its such a silly mistake
