A mass weighing 24 pounds stretches a spring 4 feet. The mass is initially released from rest at a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that gives a damping force numerically equal to two times the instantaneous velocity. Find the equation of motion if the mass is driven by an external force f (1) = 4cos 3t.
