We study the boundary stabilization of a vibrating string with an interior point mass, zero Dirichlet condition at the left end and velocity feedback at the right end. Assuming finite energy initially, we show that the energy to the right of the point mass decays like C/t while that of the point mass decays like C/√t. The energy to the left of the point mass approaches zero but at no specific rate.
