The potential energy of a particle is determined by the expression `U=alpha(x^(2)+y^(2))`, where `alpha` is a positive constant. The particle begins to move from a point with the co-ordinates (3, 3) only under the action of potential fields force. When it reaches the point (1, 1) its kinetic energy is `4 Kalpha`. Find the value of K.
