Model:
The structure is a rigid body rotating about its center of mass.
Visualize:
We placed the origin of the coordinate system on the 300 g ball.
Solve:
First, we calculate the center of mass:
cm
(300 g)(0 cm)
(600 g)(40 cm)
26.67 cm

Next, we will calculate the moment of inertia about the structure’s center of mass:
