A cylindrical buoy floating in calm seawater is depressed vertically and released, undergoing simple harmonic motion between its highest point U U\,U and its lowest point DDD. The equilibrium position of the buoy is EEE.
Which of the following quantities is at its maximum magnitude when the buoy is at EEE?
The net restoring force on the buoy
The momentum of the buoy
The acceleration of the buoy
The displacement of the buoy from EEE
