A mass weighing 12 lb stretches a spring 11 in. The mass is attached to a viscous damper with damping constant 4 lb-s/ft. The mass is pushed upward, contracting the spring a distance of 4 in, and then set into motion with a downward velocity of 4 in/s. Determine the position of the mass at any time t. Use 32 ft/s' as the acceleration due to gravity. Pay close attention to the units.
