The figure shows a system of point masses. The mass placed at each point is detailed in the table. Determine the coordinates of the center of mass of the system.
|Mass||9 kg||5 kg||4 kg||3 kg|
The points , , and on the -axis are occupied by three solids of masses 9 kg, 6 kg, and kg respectively. Determine the value of given the centre of mass of the system is at the point .
A square of side length 3 cm. Four masses of 2, 6, 3, and 2 grams are placed at , , , and respectively. Another mass of 8 g is placed at the midpoint of . Determine the coordinates of the center of mass of the system.
