Generalized force and the Lagrangian

[Hiranya Pasan]

Homework Statement

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.

Homework Equations

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

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?

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
