Question:

A rigid body of mass \(2 \mathrm{~kg}\) undergoes planar motion. At a given instant, the acceleration of its mass center is \((5 \mathbf{i}+3 \mathbf{j}) \mathrm{m} / \mathrm{s}^{2}\), and it rotates about the \(z\), axis with a clockwise angular acceleration of \(10 \mathrm{rad} / \mathrm{s}^{2}\). What are the effective forces at this instant? Where on the body are they applied?
