How can the motion of a ball connected to spring, with some initial angular velocity be described mathematically for any general initial elongation and initial velocity?
I have made some equations like of energy conservation and angular momentum conservation and Hookes' law but do not know how to proceed further.
$\begingroup$I recommend using a polar coordinate system to describe the motion. Then use either the standard Newtonian or Lagrangian methods to recover the equations of motion.$\endgroup$
