No.8 (10 points) a) A mass of 2 slugs is attached to a linear spring (suspended from the ceiling). The spring constant is k 18 lb/ft. The mass/spring system is immersed into a fluid that offers a damping force that is numerically equal to 12 times the velocity of the mass. There is no external acting on the mass. Set up the Initial-Value Problem giving the equation of motion of this mass if it is released from a point 4 feet below the equilibrium point with a downward initial velocity of 15 ft/sec. b) Solve the Initial-Value Problem found in part a). c) State (without argument) whether this mass/spring system is underdamped, cri- tically damped, or overdamped.
