A 5.1-kg mass is located at the origin, and a 2.3-kg mass is located at x = 4.9 cm.Assuming g is constant, what is the location of the center of mass x_com, and the location of the center of gravity x_cog, of the two masses? A)x_com = 1.5 cm, x_cog = 3.4 cm B)x_com = 3.4 cm, x_cog = 1.5 cm C)x_com = 1.5 cm, x_cog = 1.5 cm D)x_com = 3.4 cm, x_cog = 3.4 cm E)x_com = 1.5 cm, x_cog = 0 cm

The center of mass (x_com) is calculated using the formula: (m1*x1 + m2*x2) / (m1 + m2). Substituting the given values, x_com = (5.1*0 + 2.3*4.9) / (5.1 + 2.3) = 1.5 cm. Since g is constant, the center of gravity (x_cog) is the same as the center of mass, so x_cog = 1.5 cm.
