A mass weighing 16 pounds stretches a spring 8 3 feet. The mass is initially released from rest from a point 2 feet below the equilibrium position and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1 2 the instanteous velocity . Write the differential equation necessary to determine the equation of motion if the mass is driven by an external force equal to f(t)
