A smooth slide weighing M kg is located on a smooth horizontal floor. A puck weighing m kg was put on the slide and released without any initial exposure.
According to the assignment, we have no friction forces, therefore, there is no mechanical work.
We apply the law of conservation of energy and the law of conservation of momentum for a closed system of bodies.
As well as the equations of kinematics of the material point.
There is an "error". The puck m can't be = 0.6 M, it's too large ))))
