Question

all Verizon 22:07 session.masteringphysics.com , Home Work 2 The figure shows two vectors, A and B, whose magnitudes are A = 6.9 and B Determine C if 5.5. -Part A C=A+B Express your answer using three significant figures. Assume positive sign for the positive direction of the x-axis and negative sign for the negative direction of the x- axis. SunRequest Answer Part B Express your answer using three significant figures. Assume positive sign for the positive direction of the x-axis and negative sign for the negative direction of the x- axis. -PartC C=B-A. Express your answer using three significant figures. Assume positive sign for the positive direction of the x-axis and negative sign for the negative direction of the x- axis.

Explanation / Answer

a)

C = A + B

A = 6.9 i

B = -5.5 i

So, C = (6.9 - 5.5) i

= 1.4 m towards right

b)

C = A - B

= (6.9+5.5) i

= 12.4 m towards right

c)

C = B - A

= -(A - B)

= - 12.4 m (towards left)
