Question

Two forces FA and FB are applied to an object whose mass is 18.0 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 1.10 m/s2. However, when FA points due east and FB points due west, the acceleration is 0.500 m/s2, due east. Find the magnitude of FA and the magnitude of FB.

Answer 1

\[\vec{FA} +\vec{FB} = (18 \times 1.10)Newtons\]\[\vec{FA} -\vec{FB} = (18 \times 0.500)Newtons\]

Answer 2

Thanks!
