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.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
