# Edexcel - M3 - 18th May 2016 watch

1. (Original post by duckducks78)
someones butthurt they ddnt get a 75 lol
Aren't you still doing AS
2. (Original post by duckducks78)
nah
Brought you back to GCSE?

Q4b) 18.4 degrees

Otherwise looks pretty much what I got (I'm gradually forgetting)
Yesss that's it, I got 18.4°, what do u think I would lose from that silly mistake I mentioned? It was 9 marks including part ii which I got by using their show that so I assume part i was 7marks alone? Anyways how many you think I'd lose? Thanks
4. Q1, speed is 12/(x+3) , they ask you to find the magnitude of force when x=3
Q2, There is a right angled-triangle with 6cm and 9cm side perpendicular from each other. Work out the perpendicular distance of the centre of mass from line with 6cm (line AG)
Q3, OA=1.5=natural length, λ=12N i think? I cannot remember the mass, Paricle is dropped from the O and come to rest in a place at C, work out the distance C
Q4, a is proof, b is work out the angle between vertical and centre of mass when the sharp thing is held at one point of the circumference
Q5 and 6 I cannot remember which one is which but I just put it down anyway
Q5: There is 2 string which is AP and BP, AB length=l, the angle between AB and AP or AB and BP is 30, at the end of AP and BP there is a particle of P, the mass is m and it is rotating with w rads-1, work out the tension of AP and BP in term of g,l,w,m. Also show that the time take for the particle to rotate one rev is less than π(2g/l)^1/2
Q6. Totally forgot all the numbers but I remember the speed at the bottom is (7gl/2)^1/2, radius of the circle is l, work out the speed when the height increased to l (which is horizontal to the centre A), then it is about the particle is move in a circular motion centre A and then in the horizontal it meet a peg B, it moves another semicircle around B so prove AB is greter than 1/2 l.
Q7. Hahaha I've done this question before and I forgot all about it because I finished this one too quickly and I found not many people struggle on this,,,, so I'm too lazy to write this question lol
5. Q1 part b is work out the time when x=4 i think
Q3 part b is to work out some speed but I really forgot what is the exact question...

Ahhhhhh my memory is going bad

1) easy
2) easy
3/0 piss
4/ piss
5_ pisstake
6) so fucjing easy
7) what a joke
Trust me.
Question 8 was hard though

I like your optimistic attitude towards M3 , now it is time for you to recall the exact question of M3 because I think the kind of people like you who can get full mark will definitely have more time than others to waste the time on memorising the questions so you can prove you are really smarter than others?

Yeah you are right, I have no idea how to do question 8 because it is totally impossible... how can there be a such question exist in the world XD

Did you manage to get the result? If so, they may see it as a 'fudged' show that.

If I'm honest, it depends entirely on the mark allocation, given it's so early on that you use the radius (resolving horizontally) it's likely you'll miss all of the accuracy marks from that point on which could be a lot (5ish) or could be very few (3ish), who knows?

Edit: ignore my 5ish and 3ish that's rubbish. It's likely around 4 and 2 respectively
10. (Original post by duckducks78)
for you coz ur dumb lol
Thick as duck sh*t
11. (Original post by duckducks78)
doin STEP innit
What's the point
12. (Original post by duckducks78)
got 120 in all my STEP papers so feelin pretty confident
you need more practice
13. Hi guys, nice to see people are fairly happy after today, thought it was a standard paper really, I just made a silly mistake cause I didn't read the question

Tip: follow the invigilator and follow them till they get into the car and you carefully sneek into the car and find your paper then change it quickly, all the answers is already in this thread so be quick now or never

Don't dwell on it, it'll be fine

Focus on the upcoming exams as they're now what's important

Wish I could! Still think I've got somewhere in the 70-72 region

Thank you, I don't think it's impacted my grade too much

Well that is good!!! It is A* definitely

No I didnt I did the right thing for the wrong radius and showed so much working out however time was almost up in my exam and I decided to finish off at a point and just wrote "therefore Tension at a = show that" loool but is it allowed to use the show that to find part ii do u think? And yeah I understand thanks for this by the way
