1. https://tcan4424-oakcliff-ccl.gradpoint.com/Resour... 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:

a. 68°

b. B = A

c. B = A + (2,0)

d. B = 7.6A

e. B = 2A

3.What are the components of a vector with a magnitude of 4.00 and a direction of -112°?

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.

Question(2)

C)B=A+(2,0)

Question(3)

Component of of vector is 5.6
