Adding and Subtracting Vectors

Given m = (4, -5) and n = (-1, 2), what is m - n?

• (3, -7)

• (5, -3)

• (5, -7)

• (3, -3)

Given three vectors a, b and c as shown in the diagram. With the polygon rule, the most appropriate diagram for

d = a - b + c is

Given u = <3, 7> and v =<-5, 4>, find -u + v.

• <-8, -3>

• <8, 11>

• <-2, 11>

• <2, 3>

• (-3, -4)

• (-3, 4)

• (3, -4)

• (3, 4)

3u-4v

• <5, -4>

• <2,56>

• <-3,32>

• <11,-4>

• A

• B

• C

A = 5i + 7j , B = -6i + 2j maka

B - A = ...

• -i + 9j

• 11i + 5j

• -11i - 5j

• 5i + 11j

What is the resultant vector if the two vectors are added together? (What is the displacement?)

• <3, 6>

• <-9, -8>

• <9, 8>

• <6, 3>
