8. Mr. Shin, Mrs. Pacht, and Ms. Monte need to lift a box of calculators from the first floor. Standing in the stairwell on the third floor, Ms. Monte lifts the heavy box using a piece of rope with a force of 350 N. At the same time, Mr. Shin decides to push the box East, applying a force of 220 N, while Mrs. Pacht pushes the box South, with a force of 410 N. Using cartesian vectors, determine the magnitude of the resultant force. Make sure to include a well-labelled diagram as part of you solution. [SA]
