A system consists of three masses connected by light (effectively massless) rigid rods. The first, m1 = 3.00 kg is at a distance of 2.75 m along the y axis. The second, m2 = 4.00 kg is at a distance of 2.50 m along the x axis. A final mass, m3 = 2.50 kg, is placed at (-4.00, -3.30) m and connected to m1 and m2 so that the resulting center of mass of the system is at the origin. The entire system rotates about the origin. A force with a constant magnitude of 2.9 N is applied leftwards on m1. And a force of 9.7 N is applied downwards on m2. What is the resultant angular acceleration of the system about the origin, if angular acceleration out of the page is considered positive?
