Two forces Fa and Fb are applied to an object whose mass is 8.0 kg. The larger force is Fa. When both forces point due east, the object’s acceleration has a magnitude of 0.5 m/s2. However, when Fa points due east and Fb points due west, the acceleration is 0.4 m/s2, due east. Find (a) the magnitude of Fa and (b) the magnitude of Fb.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
