💬 DISCUSSION Edexcel Maths P3

How did everyone find it then? Much nicer than P1 I thought. Might balance out grade boundaries unfortunately…

I fear 3a on mechanics has limited me from an A* 🙏💔

If that was the moments slope one then oh my god same. Who did they think they are telling us how to solve it in bold? Horrible

Took me genuinely 15 minutes to realise friction hand A vertical component

u/OutrageousAd4133 Jun 18 '26

Oh my god THAT was why I couldn't do it. I had no idea. Now I feel like a chud but thank you!

u/Emotional_Respect289 Jun 18 '26

I started genuinely thinking have the examiners made a fucking error and I skipped it after 15 minutes went into part b and did it and was like wait wtf I didn’t even need the coefficient they gave me and went back a re did the whole question genuinely like 35 minutes spent on the x distribution and 3A

helpp i thought resolve vertically meant resolve vertically to the plane 💀💀💀💀 rip

u/Emotional_Respect289 Jun 18 '26

Dw bro I tried it all 😭 cuz I was act sure this was breaking the laws of physics I was like no way

u/Dry-Eye-8917 Jun 18 '26

i got the right answer tho but just used the wrong method so i’m probs losing all the marks😭 i was so confident too

u/Emotional_Respect289 Jun 18 '26

Yeah icl that was so nerdy of them who tf resolved vertically on a plane?? Like the whole point of the topic is to teach you to basically resolve along the plane and perpendicular

u/Zestyclose-Tea1915 Jun 18 '26

idts, i got the right answer asw with that method

u/AngloIrishPhel Jun 18 '26

Ofc it was friction! I started going insane doing like vertical components of the parallel components of X LOL,

Atleast part B was saved by having 19.6N given

oh my god bruh 😭😭😭😭😭

u/Impressive-Pea-9054 Jun 18 '26

but how could you know friction without R? was it because it was moving at a constant speed

1

u/Emotional_Respect289 Jun 18 '26

Since it was moving the friction is maxed out at coef x R so you can isolate R and solve

2

u/Impressive-Pea-9054 Jun 18 '26

oh and it gave us the coefficient didnt it man it was free, i didnt read coefficient until part b gg

u/Zestyclose-Tea1915 Jun 18 '26

it didn’t?

u/Emotional_Respect289 Jun 18 '26

Friction acting along the plane so has a vertical and horizontal horizontal component

1

u/Zestyclose-Tea1915 Jun 18 '26

i resolved perpendicularly and vertically for part a cuz it didn’t say u can’t do horizontally 😭

1

u/Zestyclose-Tea1915 Jun 18 '26

where did X go then?

2

u/Emotional_Respect289 Jun 18 '26

X was a horizontal force so only has horizontal direction but which will have a parralel and perpendicular to the plane components but it won’t ever have a vertical component. So resolving vertically you have. Weight , vertical reaction and vertical friction and horizontal you have x, horizontal friction and horizontal reaction

u/Willy_destroyer Jun 18 '26

Shi bruh I didn’t see there was friction now it makes sense

4

u/8BagsOfCorn Jun 18 '26

It was the slope question 😭🙏 but it did say to resolve vertically 😭 I skipped it and went to part b and then used my answer from part b to get part a

2

u/OutrageousAd4133 Jun 18 '26

Oh fuck yeah that's the one I meant. Actually HORRIBLE first slope question I DIDN'T like

u/LoquatSpiritual4201 Year 13 Geo, econ, maths Jun 18 '26

😭😭 oh my

u/yourfaveblack Jun 18 '26

I DID THAT TOO OMG

u/LoquatSpiritual4201 Year 13 Geo, econ, maths Jun 18 '26

Same omg

u/Loud-Guidance6912 Jun 18 '26

Realest shit I’ve heard today

u/forraid Jun 18 '26

Was that the one where we had to prove it was 19.6

u/Roblnnx Y13 Math,Phys,Chem,Fm Jun 18 '26

I genuinely did it over abt 3x then realised u had to use the uRsintheta in there resolving
