19. 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 xcom, and the location of the center of gravity xcog, of the two masses?
A) xcom = 1.5 cm, xcog = 3.4 cm
B) xcom = 3.4 cm, xcog = 1.5 cm
C) xcom = 1.5 cm, xcog = 1.5 cm
D) xcom = 3.4 cm, xcog = 3.4 cm
E) xcom = 1.5 cm, xcog = 0 cm

what is the difference between center of mass and center of gravity?

perl · Answer

ok lets do it two ways, the first way just with masses, the second with 'weights'
