A 8 pound object is suspended from a spring which stretches an additional 96 inches under the extra weight. If the object is stretched another 18 inches and released at t=0 with an external

force F(t) = 3 sin(2t) also beginning at t = 0, find a formula describing the displacement of the object. You may only use cosines in your answer.

What is the formula for the displacement of the object?
