Two Vectors, = and , Are Added Together to Form

question 54

Multiple Choice

Two vectors, = and , are added together to form the vector = + .
The relationship between the magnitudes of these vectors is given by:
C_x = 0, C_y = A sin 60° + B sin 30°
A_x and Ay point in the positive x and y directions, respectively.
-How does the magnitude of 11ea7e4c_68cb_9d4a_9a0a_67e6d0fd4d4a_TB3413_11 compare with that of 11ea7e4c_68cb_9d4b_9a0a_8503451eea8e_TB3413_11 ?

• A)A = B
• B)A = 1.7B
• C)A = 0.4B
• D)A = 0.5B
• E)A = 0.7B
