# Problem 3-25b - Vector difference - Part 2 - (C)

Determine the vector that must be added to the sum of $A$ and $B$ in the figure to give a net displacement of $4.0\; km\; \text{W}$.

Accumulated Solution

Solution $A_x$ $B_x$ $C_x$ $R_x$
(A) $5.1 \cos 71$ $6.8 \sin 52$ $C_x$ $-4$

Correct!

Which row has the correct $y$ components of the vectors?

Solution $A_y$ $B_y$ $C_y$ $R_y$
(A) $-5.1 \cos 71$ $6.8 \sin 52$ $C_y$ $0$
(B) $-5.1 \sin 71$ $6.8 \cos 52$ $C_y$ $0$
(C) $5.1 \cos 71$ $6.8 \sin 52$ $C_y$ $-4$
(D) $5.1 \sin 71$ $6.8 \cos 52$ $C_y$ $4$
