A mass of 1.25 kg stretches a spring 0.07 m. The mass is in a medium that exerts a viscous resistance of 75 N when the mass m has a velocity of 6 . The viscous resistance is proportional to the S speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive m as the 82 displacements indicate a stretched spring, and use 9.8 - acceleration due to gravity. u(t) =
