Determine the vector A – C, given the vectors A and C in Fig. 3-32 (A = 57.4).
The figure illustrates vector A= 57.4 units west of north in 28 degrees. Vector B= 40.0 units east of north but no angle, the angle is unknown. Vector C= 46.8 units goind down straight south direction.
Find magnitude and direction?????

Convert vectors A and C to their horizontal and vertical components (i.e. each becomes two vectors – one horizontal one vertical) using their length times the sine and cosine of their angles from North. Then you calculate the resulting horizontal and vertical differences for A – C. These two vectors are then converted back to a single vector, calculating the magnitude as the square root of the sum of the squares of the lengths of the two vectors and calculating the direction as the arc tangent of the two vectors.
