Rutzaba .. I am pretty sure what those peeps did is incorrect.

Since there are 14 seats in total.. and they disregarded that totally:\

imo the ways will be way more than what they have given in the answer.

Thanks for pointing it out.. I will be asking this from my sir on Monday.. guess i have a reason now to go to school on Monday

question no-3:?

easy its 12*cos(80)= Q - P*cos(60) where P equal to 12*sin(80)=p*sin(60) solve simultaneous equations

 

[Ashleyxoxo93]

why is weight component (mgsinX) not included in work done by resistance??

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

 

[ahmed abdulla]

any

easy its 12*cos(80)= Q - P*cos(60) where P equal to 12*sin(80)=p*sin(60) solve simultaneous equations

explaination please ?its easy looking at mark scheme!!

Yeah. *sigh*
But any guesses? Personally I think... maybe bcoz they took limits on t from 0 to 60... so C's were cancelled out.
Okay. Actually that makes sense to me.
