Physics vector problem (1 Viewer)

[henry08]

Could someone please explain how to do part a of question 4 (the vectors one) of the phys1121/1131 problem set 1 in the homework book? I would scan it but my printer is being gay and not wanting to scan for some reason.

i(5-(-2) +4)
j(4-2+3)
k(-6-3+2)

since it says r=a-b+c do the same thing for each direction.

Thanks, I get that one thoguh lol.

The question above (4 in my book), is the one I am having troublee with. The 'person going for a walk' one.

lol, I do PHYS1121, questions are probably different, don't think I have that question.

I do phys1131, so maybe the books are different indeed lol.

I hope you can read it.
I would scan it too, but I just bought my printer and it doesn't come with a usb cable.

Thanks, that has given me some ideas. Isn't the answer -130i -202j though according to the answer beneath the problem?

Oh yeah, I forgot the +/- direction...ooops.

EDIT: I haven't checked but I think the answers are on blackboard.
