The 1.5-lb sphere moves in a horizontal plane and is controlled by a cord which is reeled in and out below the table in such a way that the center of the sphere is confined to the path given by (x² /25) + (y² /16) = 1where x and y are in feet. If the speed of the sphere is v_A = 8 ft/sec as it passes point A, determine the tension T_B in the cord as the sphere passes point B. Friction is negligible.
