The dynamics behavior of a system is described by the equation below: 1. Why this equation represents a free response? 2. If this represents a mass-spring system, what is the value of the spring? 3. What would be the units of x(0) and \(\dot{x}(0)\)? 4. Obtain the response x(t) of the system. Show all the steps to attain full credit. 5. Calculate the natural frequency. 6. What would be \"roughly\" a graph of x(t)? provide the correct amplitude and period. \(\ddot{x} + 3x + = 0, x(0) = 1, \dot{x}(0) = 0\)
