Add Vectors Scalars

A resultant vector is

• equal to the sum of one vector.

• equal to the sum of two or more vectors.

• equal to the difference of one vector.

How should you add two vectors? (Select all that apply!!!!)

• Add them head to tail

• Add them tail to tail

• Don't bother, why bother

• Use the parallelogram method

• Add them head to head

• c₁ =2 , c₂ =-2

• c₁ =2 , c₂ =-3

• c₁ =1 , c₂ =2

• c₁ =-1 , c₂ =3

Let u = <5, 2> and v = <1, -1>.

Find u + v.

• <4, -1>

• <6, 1>

• <3, 4>

• <1, 6>

If vector h = (3,-5) and vector k = (5, 9), find the sum.

• h + k = (8,-14)

• h + k = (8,4)

• h + k = (-2,4)

• h + k = (2,-14)

Which vector equation matches the vector operation shown in the diagram below?

• u-v=w

• u-v=-w

• u+v=w

• v+u=-w

Add the vectors R + S

R < 1 , 4 , 6 >

S < 3 , 2 , -3 >

What is the magnitude of the resultant vector, r?

• 3

• 4

• 5

• 7

Which are mathematical/analytical methods of vector addition?

• Polygon Method

• Phythagorean Method

• Component Method

• Parallelogram Method

If vector a= (4, -5) and vector b= (-7, 4) Find a+b

• (3, 9)

• (-3, -1)

• (11, 1)

• (-3, -9)
