3.A spring with a mass of 2kg has a natural length of 0.5m. 25.6N of force is required to keep it stretched to 0.7m. If it is released from its equilibrium position with an initial downward velocity of 0.6 m/s, determine the length of the spring after 1s. Suppose that the spring is immersed in a fluid with damping constant of 40.
