A weight of 24 N stretches a spring 3m. Attach a 1 kg mass to the spring and release it from a point 1 m above equilibrium with a downward velocity of 5 m/sec. Assume there is a damping force equal to 4 times the velocity and that there is no external force. a. (10 points) Find the general solution. b. (6 points) Find the maximum displacement of the mass after it passes through equilibrium and graph the solution on [0,2π].
