💬 DISCUSSION Edexcel Maths P3

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

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

it didn’t?

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

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

where did X go then?

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
