A mass weighing 16 pounds stretches a spring H feet. The mass is initially released from rest from a point 4 feet below the equilibrium position, and the subsequent motion takes place in a 1 medium that offers a damping force that is numerically equal to the instantaneous velocity. Find the equation of motion x(r) if the mass is driven by an external force equal to K)-20 cos(3), (Use g-32 ft/s? for the acceleration due to gravity) *(t)= Your answer cannot be understood or graded.
