If a mass weighing 56 lbs stretches a spring 3 inches what is the spring constant? if the mass has a velocity of 2 ft/sec and this results in a viscous resistance of 69 lbs what is the damping coefficient? assume 32lb 1 slug a. what is the mass of the object? m1.75 b. what is the damping coefficient? y 34.5 c. what is the spring constant? k 224 slugs lb sec ft lb ft d. now, suppose the object is displaced upward 4 inches from equilibrium and released. create an ode in terms of the object's displacement, u(t), in feet after t seconds and its derivatives and solve for u(t). u(t) e. combine your work for solving the ode with a computer generated graph of the preview solution and upload the document below choose file no file chosen f. explain the graph of the solution in the context of the problem.
