Write a Matlab code* (script) or use Excel to determine the damping coefficient of a spring-mass-damper system with a mass of 155 kg and stiffness of 2500 N/m such that its response will die out (decay) after about 2s, given a zero initial position and an initial velocity of 10 mm/s. 1. Display the numerical value of the damping coefficient. 2. Plot the response of the system. *Turn in your Matlab code with comments
