Arope of length l is thrown over two small frictionless pulleys separated by distance d (pulleys are placed at the same height). two masses, m1 and m2, are attached to the ends of the rope. each of two masses can oscillate in the plane of the system while rope is allowed to slide. write down lagrangian and euler-largrange equations for this system.
