Problem 3-25b - Vector difference -Part 2 - (D)

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

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

No. You have  the wrong components of both \(A\) and \(B.\)
