Problem: Two forces, F1 and F2, act at a point. F1 has a point magnitude of 9.00 N and is directed at an angle of 55.0° above the negative x axis in the second quadrant. F2 has a magnitude of 5.20 N and is directed at an angle of 53.0° below the negative x axis in the third quadrant. Part A. What is the x component of the resultant force. Express your answer in newtons.Part B. What is the y component of the resultant force? Express your answer in newtons.
