A mass that weighs 8 lb stretches a spring 6 in. The system is acted on by an external force of 8sin(8t). If the mass is pulled down 3 in and then released, determine the position of the mass at any time t. Assume that the u-axis is directed downwards and g=32 fts2. Express your answer in as a linear combination of sin(at)and cos(at).
