1. (Original post by audreygal)
I found the model answers one, but would like to sit a lil mock for myself before I go to bed.

6 probably, gonna wake up early and do last minute panic revision
6 should be okay

I honestly don't think it'll go too bad, I just hope a question with two boxes on top of each other in a lift doesn't come up...
3. I feel so stupid! Thank you.

65545775[/url]]Would someone be able to teach me M1? Like I need to know the topics we will be asked about and how to answer the questions etc.
This was literally me with stats last year, walked into my maths class the day before exams....teacher asks which bits need work...opens book at page 1.... Bloody stats

is there a question similar , i can have a go at?
6. No friction if plane is smooth

If string is light there is no weight

If string is Inextensible the magnitude of acceleration is the same for both particles

If the pulley is smooth the tension in string is same on both sides

If particle moves freely under gravity then take the acceleration as 9.8 if going down

If rod is uniform the weight acts at the midpoint.

F = ma

Friction = R X mu

Distance = area

Momentum = mass X velocity

Impulse = mv - mu

Total momentum before impact = total momentum after impact

If rod is about to tilt, the other supports force is equal to 0

V = (r - r0) /t

r = r0 + tv

Velocity = (speed / magnitude of direction vector ) X direction vector

Magnitude of a vector = square root (i^2 + j^2)

V = u + at

S = ut + 1/2 X a X t^2

V^2 = u^2 + 2 X a X s

S = 1/2(u + v)t

S = vt - 1/2 x a X t ^2

knowing our luck that will be the last question
8. Did anyone who has done the very last gold paper the ultimate one actually do well......I thought I knew m1 then that ruined me.....I'm just glad every single question won't be on that level....

I'm struggling to find one but I'm sure it's came up before. I might just ignore it though because the likelihood of it coming up seems small..

it has really low grade boundaries. however, dont just correct your mistakes, you need to understand why you were wrong and why whatever was right was right

Awesome....was gonna look up the arsey revision thread but this has it all....thanks for this!

gold paper 5 if you havent done it

9AM
sure lets do an all nighter

I agree....a mistake = a gap In knowledge....it was just so many gaps all at once lol....understand it now though

well you understand gold 5 then you're definitely ready for whatever comes up!
16. Guys just a last minute panic check; if moving parallel to i, the j component = 0 and vice versa right??

And if north-west then??
17. If you get the right answer with working that is different (but still valid) from the mark scheme do you get full credit mark wise?
18. is there an error carried forward in M1?

like i do sooo many silly mistakes because of the hurry, such as signs mistakes.
especially for the questions that you have to use previous parts in........
i hope there is or i will get a zero

-i+j
20. (Original post by Alevelhelp97)
-i+j
-i+j=0 ??
then can you rearrange to get j=i

thanks
