A mass weighting 48 lbs stretches a spring 4 inches. The mass is in a medium that exerts a viscous resistance of 14 lbs when the mass has a velocity of 2 ft/sec. Suppose the object is displaced an additional 6 inches and released. Find an equation for the object's displacement, u(t), in feet after t seconds. u(t)= 0.333e COS 47.096 2 t +0.3397e t sin 47.096 2 tx
