Jcole if he focused on his maths class

[@Ojisgay]

Jcole if that one girl wasn’t in his maths class😔

[@geopaxo]

I hate mechanics but when all lots of variables cancel to give a round number it’s so satisfying!

[@johnegemole2646]

What a guy, maths icon!

[@saidbenrahma9129]

what a legend!! elite ranking in FUT champs :)

[@MrAstburyMaths]

You know it! FUT17 POTM Sonaldo OP 😄

[@marissa4154]

ladders beautifully explained

[@jkim1402]

Thats what im sayinggg

[@idontknowwhattonamethis75h82]

in Q1, C you have concluded that acceleration is equal to 0, however can we assume this if it asks about why it will be at rest

[@alexanderpowell6823]

ur in radians at 41:23

[@moa7651]

Thanks for that ladder q

[@Sylantjfjcx]

Earned a sub 🐐

[@hhhh13523]

for question 5 I tried doing it another way but it did not work, could you tell me where I am going wrong. work out time for horizontal to reach 50m (100/square root 2 U). then substituite that T value in V= U + at with v=0 (as at greatest height the vertical velocity=0) U= Usin45. a= -9.8 I don't understand why I get a different value of 31 instead of 28

[@jennaaa-21]

on question 4, why did you resolve the force 'mg' into : mgcosA and mgsinA, i dont think your supposed to resolve it when theres no particle acting on it no?

[@laiilaaaaaaa]

how do you get an answer to 1d? 😭

[@madbantmatt7965]

For Q4 (a) in mechanics, why couldn’t you let Nsin(α) x 4a = Mgcos(α) x 3a and rearrange for N?

[@user-pl5oy8dj5t]

Nsin is not the perpendicular distance to the rail. Remember a moment is perpendicular distance multiplied by distance

[@mohzayd1234]

Hello. I can’t find the 2022 papers walkthroughs anymore, where they removed?

[@MrAstburyMaths]

The papers will be up soon! In the mean time I have 2021 and 2020 available

[@maliks_]

​@@MrAstburyMaths can u reupload 2022 stats and mechanics really quickly please i urgently need it😭😭

[@ItzSlashyyy]

ty

[@SeaCashew-jr7sg]

why did you need to take moments for N (29:35) but not need to take moments for F, why couldnt you have just set N = the opposite force like you did with the friction

[@CyberHabibi]

40:46 bro left his calculator in radians

[@Luke-uy2zu]

Legend

Thanks for the support 🙏
