The small particle of mass m = 3.8 kg and its restraining cord of length r = 0.46 m are spinning with an angular velocity ? = 1.6 rad/s on the horizontal surface of a smooth disk, shown in section. as the force f is slowly relaxed, r increases and ? changes. when r = 0.63 m, what is the angular velocity
