Q1. Two forces FA and FB are applied to an object whose mass is 5.43 kg. The larger force is FA. When both forces point due east, the object's acceleration has the magnitude of 1.40 m/s2. Though, as FA points due east and FB points due west, the acceleration is 0.747 m/s2, due east. Find

(a) magnitude of FA and (b) magnitude of FB.
