# Problem 3-25b - Vector difference -Part 3 - (D)

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) $5.1 \cos 71$ $6.8 \sin 52$ $C_x$ $-4$

Solution $A_y$ $B_y$ $C_y$ $R_y$
(D) 5.1 sin 71 6.8 cos 52 $C_y$ $4$

No. You have the wrong sign for $A_y$ and the wrong value for $R_y.$
