The masses shown below are held together by rigid, massless rods, and arranged at the corners of a square that is 15 cm on all sides. The moment of inertia I of the square if it was rotated around Mass 1 in the xy plane (the plane that contains all four masses) is kg* m ? Turn in your calculations for this question for 3 points on your calculations sheet. M2 = 5.0 kg MA = 1.0 kg M, = 2.5 kg M3 = 4.0 kgIf the rotation in the previous problem has a rotational kinetic energy of 250 J, then it is rotating at an angular speed of w =_ rad/s.
