Two forces FA and FB are applied to an object whose mass is 19.8 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 0.997 m/s2. However, when FA points due east and FB points due west, the acceleration is 0.587 m/s2, due east. Find (a) the magnitude of FA and (b) the magnitude of FB . (a) Number Units (b) Number Units
