The potential energy of a particle is determined by the expression $\mathrm{U}=\mathrm{\alpha }\left({\mathrm{x}}^2+{\mathrm{y}}^2\right)$, where $\mathrm{\alpha }$ is a positive constant. The particle begins to move from a point with coordinates (3, 3), only under the action of potential field force. Then its kinetic energy T at the instant when the particle is at a point with the coordinates (1, 1) is
