A disk with a mass of 3 kg hangs on an elastic cord with a stiffness of 200 N/m attached to the center of the disk. Along the cord, from a height of 80 cm, a washer (with a hole in the center) weighing 1 kg falls flat onto the disk. How far (in cm) will the disk fall after the puck falls? The impact of the puck on the disk is completely inelastic. g = 10 m/s2.
