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

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

diagram indicating directions north and east as well as vectors A and B

Accumulated Solution

diagram indicating C at the desired 4 km West

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

 

Solution \(A_y\) \(B_y\) \(C_y\) \(R_y\)
(C) \(5.1 \cos 71\) \(6.8 \sin 52\) \(C_y\) \(-4\)

No. Those are the \(x\) components.
