I tried to use Lagrangian and Hamiltonian to solve 1-D elastic collision, but I got nothing but constant velocity motion. Is it because I miss some constraint? Such as the motion is colinear or something?But how to write a constraint like colinear?
Or it's not actually solvable with Hamiltonian or Lagrangian?(I think this is a possibility because when I learned Newtonian mechanics we actually didn't solve this with Newton's 3 laws directly, but with conservation laws.)
