Two forces, F1 and F2, act at a point. F1 has a magnitude of 9.80 Newton and is directed at an angle of 60 degree above the negative x axis in the second quadrant. F2 has a magnitude of 6.40 Newton and is directed at an angle of 53 degree below the negative x axis in the third quadrant.
Part A Determine what is the x component of the resultant force?
Part B Determine what is the y component of the resultant force?
Part C Determine what is the magnitude of the resultant force?
