Extracted text: A mass weighing 16 pounds stretches a spring 8 feet. The mass initially released from the equilibrium position with a downward velocity of 4 ft/s. The motion takes place in a medium that offers a damping force numerically equal to 2 times the instantaneous velocity. (a) Find the equation of the motion. (b) Find the value(s) of the extreme displacement. (c) Determine whether the mass passes through the equilibrium position
