A 30-pound mass of weight stretches a spring to a 10-foot spring, if the medium surrounding the system has a damping coefficient, that is, it is equivalent to 5 times the instantaneous speed and the weight is released from a point located at 16 inches below equilibrium position with an initial velocity of 1 foot per second down. A) Deduce the Differential Equation that models the mass-spring system. b) Calculate the displacements (t) at all times t.

An 8-pound weight is attached to a spring hanging from a ceiling. The weight stretches the spring 9.6 inches, coming to rest at its stretched equilibrium position. The weight is displaced 8 inches below this stretched equilibrium position, and at time t = 0 the mass is released. At the same instant, an external force of F(t)= 2cos(2t) pounds is applied to the system. The damping constant is 1 lb/(ft/sec). Find the function that gives the displacement of the mass...
