Help in Q23 . JUne 2006 P2 > plz
its making me lose my mind..
Thanks in advance
23 a) VW = a + b
simply because VW is in the same direction as a and b
ii)TU = a - b
TU in the same direction as 'a' but opp. to 'b'
iii) is attached .. its a bit complicated ..
wonder how i got UA as 'b'
VA is clearly b-a
so 'UA' + AV should be equal to "a"
so UV = UA +
AVa = UA + a - b
so UA = b
same stuff for BP WB also which gives us a
so adding UA , AB , BP and TU u get TP
=b + (a +b) + a
= 3a +b
gosh pls. dont freal out if u dont understand .. i did my best to explain ..
iv) from origin position ov p is 1/2 TP
= 1.5a + 1/2 b
v) is simply count no. of blocks of TU = 4
