16. Calculate the magnitude of the resultant force in each case below. A vector F1 has a magnitude of 40.0 units and points 35.0° above the positive x axis. A second vector F2 has a magnitude of 65.0 units and points in the negative y direction. Use the component method of vector addition to find the magnitude and direction, relative to the positive x axis, of the resultant F = F1 + F2
