The mass-spring system is described by the equation y" = -3y – cy'; c > 0 is the drag coefficient. (a) For c = 2, find the solution with initial conditions y(0) = 0, y' (0) = 1. Show that the system will oscillate near the equilibrium (i.e. y will change its sign infinitely many times). (b) For c = 4, find the solution with initial conditions y(0) = 0, y' (0) = 1. Show that y(t) will be positive for all t >0 and will tend to the equilibrium y = 0 as t → +∞.
