Two forces FA→ and FB→ are applied to an object whose mass is 15.6 kg. The larger force is FA→. When both forces point due east, the object's acceleration has a magnitude of 0.771 m/s2. However, when FA→ points due east and FB→ points due west, the acceleration is 0.647 m/s2, due east. Find (a) the magnitude of FA→ and (b) the magnitude of FB→.
