Exercise 2.4.2: consider a mass and spring system with a mass m = 2, spring constant k = 3, and damping constant c = 1. a) set up and find the general solution of the system. b) is the system underdamped, overdamped or critically damped? c) if the system is not critically damped, find a c that makes the system critically damped.
