Summary: Direct and inverse spectral problems for a smooth string with massive end (with concentrated mass at the end) moving with damping is considered. By means of Liouville transformation the problem has been reduced to the Sturm-Liouville equation with boundary conditions depending on the spectral parameter. So the V.A. Marchenko formalism proves to be a powerful tool of investigation. It is shown in this paper that the spectrum of vibrations and the length of the string are sufficient for finding all the parameters of the problem.
