An SDOF undamped structure (i. e., c = 0) with lateral stiffness 150 k/in and a weight of 1200 kips is undergoing free vibration after being exposed to an initial velocity of 2 in/s and an initial displacement of 4 inches. For each 0.1 second time increment up to 1.2 seconds, find the acceleration, velocity and displacement of the structure. Plot the acceleration, velocity and displacement time history of the SDOF oscillator and label the maximum amplitude and fundamental period on each plot.
