A mass of 2 kg stretches a spring 0.07 m. The mass is in a medium that exerts a viscous resistance of 23 N when the mass has a velocity of 2 The viscous resistance is proportional to the speed of the object. m - S Suppose the object is displaced an additional 0.03 m and released. m Find an function to express the object's displacement from the spring's natural position, in m after t seconds. Let positive displacements indicate a stretched spring, and use 9.8 gravity. as the acceleration due to $2 u(t) = Submit Question
