i havent been able to figure this one out... i have trouble following the explantion from my instructor. thanks for any help in advance A rigid object consists of a point mass of 2 kg momentarily located at (-3, 2) m with a force of (6, 2) N acting on it, a second point mass of 3 kg momentarily at (6, -2) m with a force of (3, -4) N acting on it, and a third point mass of 1 kg momentarily at (-2, -5) m with a force of (5, 5) N acting on it. Suppose this rigid three-particle object can only rotate about an axis passing through the origin and perpendicularly the x y plane. (This means the axis also exerts forces on our rigid object.) What is the angular acceleration of our rigid object about this axis?
