You're welcome x)



Thank you, my brain stopped e_e

You're welcome happens to everyone at some point I guess

may june 2009 question 1 c)ii) my answer is different than the mark scheme and i can't get the write answe

You're at the wrong thread hun. This is A levels. You should head over to IGSCE

 

[roudina]

ah ok sorry

 

[GorgeousEyes]

June011 v.43 no.4 and no.5 please ,, Honestly they are the worst questions ever

 

[ZainH]

Oh righttt.. i was using B to C... -_-
Anyways q4(ii) same paper?

Just add up your values of the forces in the y-direction , and they've already given you the ones in the x-direction.
Use Pythagoras to find resultant, and then use whatever to find the angle .

Hope you got it x)

 

[AlishaK]

Which variant is tougher, 41 or 43 ?
Lemme know ASAP! Thanks a lot.

Solved that earlier in the thread, it's like 4-5 pages back.

for keeping the block equilbrium a frictional force must act on the block in the right direction
so 6.1+5cos theta=f
f=7.5
2)f=ur
r=12.5
3)7.5-8.6-5cos theta=ma

I'll be here till like 11, which is 3 more hours I guess.

According to you?

I don't knw how to resolve it :S

 

[Pie-man]

According to you?

well i think v.43 just because they have lower curves but personally i dont see any difference

 

[Anika Raisa]

Emm, I registered and there's no email in my inbox.

Thats weird! Or may b u dnt nid to check ur inbox wat msg do they give wen u register by fillin out details? A few moment back i studied vector from dere!!! n i had ma account last year so i dnt remember much! :~

Yeah they're all the same to me too

Anyone , with steps pleasee ??

 

[ZainH]

Anyone , with steps pleasee ??

Uhm, give me like 2 minutes. I'll brb.

 

[lee mee..]

Phyzac solved this one for me. Here

Thank you sooo much

43 is a bit wierd thou. :/ Anyhow, what is your real variant?
