Multiple Concept Example 9 provides background pertinent to this problem. The magnitudes of the four displacement vectors shown in the drawing are A = 18.0 m, B - 10.0 m, C = 11.0 m, and D-28.0m. Determine the (a) magnitude and (b) direction for the resultant that occurs when these vectors are added together. Specify the direction as a positive (counterclockwise) angle from the +x axis. 20.0 35.0 50.0 8.98 Units m (a) Number (b) Number Me 89.70 Units eTextbook and Media
