SUMMARY

The discussion centers on the application of Lagrangian equations in deriving equations of motion for a system. It confirms that one can determine the acceleration of a system (acceleration of x) by solving the equations of motion and applying a specific boundary condition for position (x). The necessity of additional information for solving the differential equation is also highlighted, indicating the complexity involved in practical applications.

Just a question on interpretation of lagrangian equations. If I have derived the equations of motion for a system and the equations are in terms of position of x and acceleration of x, am i able to find the acceleration of the system (acceleration of x) if I have a value for the position (x)?

You'd have to solve the equations of motion and then impose the value you have as boundary condition.

If you need help solving the differential equation, you'll have to give us some more info.
