- A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 66 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 natural position, in m after t seconds.
