An object of mass m-4 kg sliding on a horizontal frictionless surface is attached to one end of a horizontal spring of spring constant k=2000 N/m which has its other end fixed. If the speed of the object as it passes through the equilibrium position is 4 m/s, what is its speed (in m/s) when it is a distance of 10 cm from the equilibrium position?
