Two forces FA and FB are applied to an object whose mass is 9.39 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 1.40 m/s2. However, when FA points due east and FB points due west, the acceleration is 0.950 m/s2, due east. Find (a) the magnitude of FA and (b) the magnitude of FB
