Transcribed Image Text:2. A railroad car of mass 2,000 kg traveling at a velocity v = 10 m/s is stopped at the end of the tracks by a spring-
damper system. If the stiffness of the spring is k =180 N/mm and the damping constant is c = 20 N-s/mm,
determine (a) the maximum displacement of the car after engaging the springs and damper and (b) the time taken
to reach the maximum displacement.
