Assigned on 05.10.2009 Monday Due date 12.10.2009 Monday, beginning of the lecture ME429 Fall 2009 HW1 You are expected to provide clear explanation of each step in your solution, units, well annotated scaled plots (title, axis labels, units, . .), not random hand sketches, source code attached to your solution if you use a software package. 1) A mechanical system consists of an elastic spring with a constant of 250 N/m supporting a 2 kg mass. The mass is given an initial velocity of 5 m/s in the direction of positive displacement. For this system a) determine the response, x(t) of the system for
