A pulley (in the form of a uniform solid disk) with mass Mp and radius R is attached to the ceiling and rotates with no friction about its pivot. Mass M2 is bigger than mass m1, and they are connected by a massless inextensible cord. T1, T2, and T3 are the magnitudes of the tensions in the cords, as shown. The cord does not slip on the pulley.

Which statement is true about the center of mass of the system of the pulley, and m1 and M2?
What is the relationship between T3 and the masses?
