69) A 240-lb. weight stretches a spring 12 ft in equilibrium. It is attached to a dashpot with damping constant c = 40 lb-sec/ft. The weight is attached to a winch which pulls it steadily downward with a force of 10t + 30 lbs at time t. The weight is initially displaced 5 feet above equilibrium and is then let go, without any initial push. Find the displacement for t> 0.
