just saw this so sorry for the delay and sorry for not solving it but here is all you should do, make a resolution of the forces (tensions A and C) as B is the center, so now you have both equal to 8 (horizontally) and both equal each other (vertically), and by substitution you get both tensions...- Pie-man

Best Quotations
my favorite 2 from rocky : Let me tell you something you already know. The world ain't all sunshine and rainbows. It's a very mean and nasty place, and I don't care how tough you are, it will beat you to your knees and keep you there permanently if you let it. You, me, or nobody is gonna hit... -

sorry for the delay but here you go: first get the distance using "s=1/2 x (u+v) x t" to get s= 10 then use D - R =ma so 9.336m - 1.416m = ma so a = 2.167 then use v^2=u^2 + 2 as V^2= 2 x 2.167 x 10 so v=6.58 -

i like how you emphasized that it was paper 3 xD the people that take paper 3 in this forum (of which i know about) will be online soon so solve more equations until then. good luck :) -

well they both started from rest with same conditions (driving force resistance etc...) -

the whole thing sounded gibberish to me....then i realized its paper 3 :D -

ok i'm too lazy to solve it right now :sleep: so in about 15mins or so i'll attempt it :D -
i just like arms :p (referring to your avatar or else that would be creepy) :D

why t-2 and not t+2 as it is 2 seconds late? -

yeah that i have no idea why i did that same mistake the first time i did it .. i was actually waiting to see if you would tell me :/ -
Mathematics: Post your doubts here!
i did this like a few pages back : so here is what i did (the correct one): 1- i got the equation for Sp "1/2 x a x (t+2)(squared)" 2- started to get rid of the brackets "1/2 x 1.75 x (t(squared) + 4t +4) = 0.875(t(squared) + 4t + 4) = 0.875t(squared) + 3.5t + 3.5 3- got an expression for... -

well in 6 i) you use the F.E. = I.E. as there is no driving force (he didn't mention one) nor resisting force (as it is a smooth plane) in ii) i'm thinking of getting the I.E. of C (which get you the work done against friction) and F.E. at the mid point where the V is will be the only unknown... -

all i know is if you have 3 different forces on an object you can use lami i'm not exactly sure why i got CP2X it just made more sense to me and after getting all the other angles i was sure it was right but it will make more sense if you turn it into a triangle (well for most people i know) -
i wanted to say nice name and matching avatar but everyone already said that :(
