Part i. second order equations (12+12 points) 1. (12 points) a 2 kg mass is attached to spring with stiffness 8 n/m. the damping constant uilibrium poin for the system is 10 n-sec/m. if the mass is moved 2 m to the right of the equnio and released, then find the following: a) the equation of motion of the mass (show your work in detail). b) the displacement after 3 minutes (show your work in detail).
