Three small balls of mass 3.6 kg, 2.4 kg, and 3.9 kg are connected by light rods laying along the y-axis. The rod connecting the first and second balls is 4.8 m long and the rod connecting the second and third balls is 2 m. The entire system rotates around the x-axis, which is between the first and second balls and a distance 2.9 m from the first ball, at a rotational speed 2.6 s-1.
(a)What is the distance of the center of mass of the system from the first ball?
(b)What moment of inertia of each ball around the center of
mass?

(d) What is the moment of inertia due to the shift of the
rotational axis from the center of mass to the x-axis?
