Graph the function x(t) together with the "amplitude envelope" curves x = -Cje-P and x = Cie-pt . Now assume the mass is set in motion with the same initial position and velocity, but with the dashpot disconnected ( so c = 0). Solve the resulting differential equation to find the position function u(t). In this case the position function u(t) can be written as u(t) = Cocos(wot - do). Determine Co, wo and do . Co = wo = ao = (assume 0
