A2 Mechanics (maths p5)

[angelicsuccubus]

Please tell me there's someone doing A2 mech in the entire forum! Cause in the math's thread I only see people talking about stats... =/

I am taking mech 2 tomorrow, really scared !!

 

[raihan1904]

i know its really tough!! gonna take it next year.... best of luck to u guys

I wish I could do all the modules in A Level Mathematics. Too bad that my school allows us to appear for S1 only.

my school is also the same it teaches S1 for AS n M1 for A2!!! but if we wish to take other modules we will have to do it by ourselves

But I guess that even CIE only gives the option of doing just 4 modules in whole A level. =/

Lol, I think you should really be happy that you dont have m2 tomorrow but its appreciated that you replied even though you dont do the paper =]

Guys, do u think they'll change the pattern? Make questions harder!? I HOPE NOT!!!
I'm soooo worried. :S

I have no idea.. m1/p3 were pretty hard and p1 was kinda new so probably yeah

It'd have been great if we could do s1, s2, m1 and m2 all together.

 

[mybch]

can anyone explain 4 (iii)

can anyone explain 4 (iii)

Sure...
The centre of mass will be just above the point where the cylinder's edge meets the Horizontal.
And so u take an angle ( Alpha) which will be with the height of cone and the horizontal. That'll then be common for two triangles.
And then using totals moments about Pointed part of the cone, u add up the weights..multiply that by what's given as VG...

I'm sorry tho...really can't explain mechanics in words liked this. :|

That sure would be great!!!

 

[mybch]

can you show working and upload if you don't mind?

lol why do u wanna complicate ur life by takin these many math modules??

 

[raihan1904]

even i also think that ( i know its too rude to say lyk this but its truth)
evn the world topper from our school in maths finds M2 as tough so why wont we!! n even M1 was tough even aftr i studied the whole year

If you see it as "complicated" you wouldn't have done a-levels. Period.

It's called learning, yo. Wanting to know more. As I studied only mechanics, I know nothing whatsoever about statistics.
