(1 point) Consider the spring mass system defined by the differential equation m\" + ky = Ema) If m = 0.25 kg, and the periodic Ema) shown on the graph below is applied as an external force, what value of k will result in the mass showing ever-increasing amplitude oscillations over time? If no choice of k will produce this result, put zero in Webwork, and explain your rationale on your written submission
