The mass of a g en critically damped system is released at time t-o rrom the posit on xo = 40 mm with a negative initial velocity. The mass m is 13 kg and the spring constant k is 836 N m. Determine the critical value or the initial velocity Gode below which the mass will pass through the equilibrium position Answer: (to,--371.52 the tolerance is t/296 -371.87 mm/s)
