An iron ball weighing 0.8 kg hangs on a spring with a stiffness of 103 N/m. From the side of an alternating magnetic field, a force varying according to a sinusoidal law acts on the ball, the amplitude value of which is 2.0 N. The quality factor of the system is 30. Determine the amplitude of forced oscillations in cases where w = w0/2; w=w0; w=2wo-
