Amass weighing 16 lb stretches a spring 8/5 ft. the mass is attached to a viscous damper with a damping constant of 2 lb- sec/ft. the mass is set in motion from its equilibrium position with a downward velocity of 5 in/sec.
find the position x of the mass at any time t. plot x versus t. if a force of 0.5 sin (2t) exerted to the system, describe the motion after a very long period of time.
