A pendulum is constructed of a mass m connected to a mass ess rigid rod of lengthl. As shownin the figure, the other end of the rodis suspended from a point on the ring of radius R. The pendulum is free to swing in a vertical plane that is also the plane of the ring. The ring rotates with constant angular velocity w about the horiontal axis that passes through the center. What is(are) the appropriate generalized coordinate(s)for the system and find the lagrange equation(s) of motion for the system. {Hint: Find horizontal and vertical position of mass m and then calculate velocities vx and p Calculate vy
