cat toy of mass 1 kg is attached to a spring hanging from a fixed support. The displacement of the mass below the equilibrium position, y(t), can be described by the homogeneous second order linear ODE y"(t) + 3y (6) + ky(t) = 0, > 0. Here, k denotes the spring constant. (a) For which values of k is the system underdamped, critically damped, overdamped? add any extra pages after page 6
