Are there any ignorable coordinates in this scenario?

I don’t think so right, because the lagrangian has explicit dependency on both x and theta. Ignorable coordinates means there is no explicit dependence of that coordinate right?

If there are no ignorable coordinates that also means there are no constants of motion?

Since the Euler-Lagrange equation has d/dt(partialL/partial q_i dot) = partialL/partial q_i and none of the partial L/partial q_i’s are 0 then there are no constants of motion right
