A spring is stretched by 7in by a mass weighing 15lb. The mass is attached to a dashpot mechanism that has a damping constant of 0.1lb⋅s/ft and is acted on by an external force of 5cos(9t)lb. Determine the steady state response of this system. Use 32ft/s2 as the acceleration due to gravity. Pay close attention to the units.
