Generalized force and the Lagrangian

  1. Dec 3, 2016 #1
    1. The problem statement, all variables and given/known data
    A particle of mass m slides without rolling down on a inclined plane, Find the generalized force and the Lagrangian equation of motion of mass m.

    2. Relevant equations
    T = (mx'^2)/2
    Generalized force Q=-d/dx(V)

    3. The attempt at a solution
    To find the generalized force first I found the Potential energy and taking the derivative with the x, but my teacher said that the friction force should take into the account therefore I was told using the Work done, find the generalized force. How can I do that?

    Your issues seem to suggest there is more to the problem than what you state. Please post the entire problem statement quoted word by word.

    Thanks for the response , This is the entire probelm, but the angle of inclined plane can be taken as theta and we can take parameters as necessary
