Ok, there are two objects of mass m on a frictionless table. The 2 masses are connected to the other by a spring of spring constant k. One mass is connected to a wall with a spring of the same constant k. Solve for the motion using Lagrange' s equations.(adsbygoogle = window.adsbygoogle || []).push({});

I used generalized coordinates x starting from the centre of the mass closer to the wall and y starting from teh center of the mass farthest from the wall. I get T = (1/2)mxdot ^ 2 + (1/2)mydot ^ 2

V = (1/2)kx ^ 2 +(1/2)k(x-y) ^ 2

I know that this contains cross terms but uptill this stage , is it correct?
