haha xD me with computing seems french to mee too gdlckugghh i m stuck in bio ryt now.... =/ -__- cant even seem to comprehend wat that question is
can i take a rain check on this one?

haha xD me with computing seems french to mee too gdlckugghh i m stuck in bio ryt now.... =/ -__- cant even seem to comprehend wat that question is
can i take a rain check on this one?
easy its 12*cos(80)= Q - P*cos(60) where P equal to 12*sin(80)=p*sin(60) solve simultaneous equations
here c is the constant of integration but still i'm confused how hey took it 0Q.5 (ii)
How can we prove the highlighted section? I don't get it.
Question # and paper # pleasewhy is weight component (mgsinX) not included in work done by resistance??
explaination please ?its easy looking at mark scheme!!easy its 12*cos(80)= Q - P*cos(60) where P equal to 12*sin(80)=p*sin(60) solve simultaneous equations
Yeah. *sigh*here c is the constant of integration but still i'm confused how hey took it 0
Question 6Question # and paper # please
Equations formed are basically resolving of the forces. First ie 12*cos(80)= Q - P*cos(60) is resolving in the x axis.any
explaination please ?its easy looking at mark scheme!!
tanks broEquations formed are basically resolving of the forces. First ie 12*cos(80)= Q - P*cos(60) is resolving in the x axis.
Consider all forces and their individual components first.
In x axis:
For Q: It's Q.
For 12N (aka the Resultant) = 12cos(80) N
For P: Pcos(60) N
(60 = 180 - (80 + 40) )
In y axis:
For Q: ZERO - Nada - Zilch.
For 12N (aka the Resultant) = 12sin(80) N
For P: Psin(60) N
Now equate all of these.
Resultant = vector sum of force components
In x axis:
12cos(80) = Q - Pcos(60) (i)
Similarly, y axis:
12sin(80) = Pcos(60) (ii)
First find P from (ii).
Substitute it into (i)
Voila u get Q.
component in X and y Directionsany
explaination please ?its easy looking at mark scheme!!
the fastest way is to use lami's rule to get the angle opposite to P1 then get the angle AP1X using subtraction from 360 degrees, then lami again to get the value of W.http://papers.xtremepapers.com/CIE/...S Level/Mathematics (9709)/9709_w10_qp_41.pdf

Q3 How to solve this. I couldn't attempt this one at all. Please help me out

its 7 (iii) ? Cant just get it Need help
JazakAllah
Since you're seeking me out... answers to parts (i) and (ii) are...?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
