Q. 1.279 A small disc and a thin uniform rod of length l, whose mass is η times greater than the mass of the disc, lie on a smooth horizontal plane. The disc is set in motion, in horizontal direction and perpendicular to the rod, with velocity v, after which it elastically collides with the end of the rod. Find the velocity of the disc and the angular velocity of the rod after the collision. At what value of η will the velocity of the disc after the collision be equal to zero? reverse its direction?

Key Point of Dynamics of a Solid Body:
-
The dynamics of a rigid body system are defined by the kinematics laws and the application of Newton's second law (kinetics) or their Lagrangian mechanics' derivative form.
-
The solution of these motion equations provides a description of the position, motion, and acceleration, as a function of time, of the individual components of the system and of the system itself as a whole.
-
An important tool in computer simulation of mechanical systems is the formulation and solution of rigid body dynamics

Important Topics Covered in Physical Fundamentals of Mechanics IE Irodov:
Rigid-body dynamics studies the movement of interconnected-body systems under external forces. The presumption that the bodies are rigid, meaning that under the action of applied forces they do not deform, simplifies the study by reducing the parameters that characterize the system's configuration to the translation and rotation of the reference frames attached to each object. This excludes bodies that display fluid, plastic behavior, and highly elastic.
