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

  • physical - ,

    Using Newton's second law: F=ma
    m=9.39 kg


    Fa=(13.146+8.9205)/2=11.03 N
    Fb=(13.146-8.9205)/2=2.11 N
