A spring, suspended vertically, elongates by 0.02m when a mass of 0.08 kg is attached to it. An object of mass 0.6 kg is attached to its free end and it is displaced by 8 cm from its equilibrium position. Determine the energy of the system at this position. From the viewpoint of energy, determine the velocity of the body when it is at a distance of 0.04 m from the equilibrium position.

1.	A spring, suspended vertically, elongates by 0.02m when a mass of 0.08 kg is attached to it. An object of mass 0.6 kg is attached to its free end and it is displaced by 8 cm from its equilibrium position. Determine the energy of the system at this position. From the viewpoint of energy, determine the velocity of the body when it is at a distance of 0.04 m from the equilibrium position.
