Suppose a spring with spring constant 2 \ \mathrm{N/m} is horizontal and has one end attached to a wall and the other end attached to a 4 \ \mathrm{kg} mass. Suppose that the friction of the mass with the floor (i. e., the damping constant) is 2 \ \mathrm{N \cdot s / m}. Set up a differential equation that describes this system. Let x to denote the displacement, in meters, of the mass from its equilibrium position, and give your answer in terms of x, x^{\,\prime}, x^{\,\prime\prime}. Assume that positive displacement means the mass is farther from the wall than when the system is at equilibrium. 4*x'' 2*x' 2x
