I can help, what have you done to answer these?
As well as this:
9. v can be broken down to y = sin40 x 5 and x = –cos 40 x 5
w can be broken down to y = 2 sin55 and x = 2 cos 55
now we want to replicate w, to match y, 5 sin40 / 2 sin 55 = 0.5 of v is needed
to match x, (2 cos 55 + 5cos 40 )/4 = 1.24 of u is needed (but in the opposite direction tho),
so w = 0.5 v -1.24 u
But I had help from my friend who can skip steps really quickly and so what I really want to know is the steps...
