(a) Determine the location of the center of mass of the system shown in Figure P6.38. All three disks are made of sheet metal of the same material, and the diameters are \(1.0 \mathrm{~m}, 2. 0 \mathrm{~m}\), and \(3.0 \mathrm{~m}\).

(b) Repeat the calculation for three solid spheres all made of the same metal and having the same diameters as in part \(a\).
