A 5-kg mass is attached to a spring with stiffness 140 N/m. The damping constant for the system is 20 StartRoot 7 EndRoot N-sec/m. If the mass is pulled 30 cm to the right of equilibrium and given an initial rightward velocity of 3 m/sec, what is the maximum displacement from equilibrium that it will attain?
