Question

Vector A = 5.10 m points 43 deg north of east. Vector B = 6.80 m points 139.6 deg north of east. What is the magnitude of the resultant vector A+B?

Answer 1

thats what it says. it is an online assignment. i think it much be a type. it must be east of north.

Answer 2

typo*

Answer 3

yes lol

Answer 4

thats what ive drawn

Answer 5

im confused, so the magnitude is 8.5m?

Answer 6

came up wrong.. it said "Be careful with East of North and North of east!Draw a picture. "

Answer 7

139.6 northeast?? where is it?

Answer 12

???

Answer 13

Normally when you deal with those measures, they are restricted to 0 to 90. So 0 to 90 north of east or 0 to 90 north of west, etc.

Answer 14

I don' t get

Answer 15

And also, they are generally with north and south first. It is a form of measure called compass quadrant bearings when they say something of something.

Answer 16

I think the question meant to be this:

Vector A = 5.10 m points north of east at 43 deg. Vector B = 6.80 m points south of east at 139.6 deg. What is the magnitude of the resultant vector A+B?

But I can't be completely sure. It is very poorly written.

Answer 17

it is.

Answer 18

Only if they really meant at. If they did not, then:
