In this video, I use the skills we've developed in the previous videos on Calculus of Variations/Analytical Mechanics to solve an Action Problem involving a block sliding down a moving inclined plane.
I begin by formulating the problem, determining the kinetic and potential energies, and then solving the Lagrange equations for the 2 'particle' (i.e. block + wedge) system.
