1. Vector C is multiplied by the scalar −2. What angle does the new vector make with the y-axis?

2. The components of vector A and vector B are:

Ax = + 7.6 Bx = +15.2
Ay = -9.2 By = −18.4

Which equation describes the relationship between the two vectors?

a. 68° 

b. B = A

c. B = A + (2,0)

d. B = 7.6A

e. B = 2A

According to given question

angle does the new vector make with the y-axis

Dot productB • C = |B| |C| cos θ 

θ = arccos ( (B•C) / (|B| |C|) ) 
= arccos ( (4.8*5.6) 
= 105° Ans. 




Component of of vector is 5.6
