A vertically suspended body with mass, M=12 kg is attached to the end of a spring that is stretched 0.098 m by the body. The body is also attached to a vertical dashpot that provides 2 N of resistance for 2 m/s velocity. It is set in motion from 1 m above
the equilibrium position with a downward velocity of 5 m/s.
Find the position function of the body as well as the damping condition, time-varying amplitude, natural frequency, and phase shift.
