An object weighing 56 Ibs hangs on the end of a spring, stretching the spring 6 inches. The object is in a medium that exerts a viscous resistance of 12 lbs when the object has a velocity of 4 ft/sec. Suppose the object is lifted an additional 3 inches and released. Find an equation for the object's displacement, u(t), in feet after t seconds. u(t) = Remember that, in imperial units, acceleration due to gravity is 32 ft/s2 and that Ibs are a measurement of force. Be sure to convert any measurements necessary so that the units match.
