The mass is then pulled downwards through a further distance of 20mm and released so that it oscillates about the static equilibrium position. 

Hope you like the complete free solution!

A close-coiled helical spring undergoes a static deflection of 30mm when a mass of 2.5 kg is placed on its lower end. The mass is then pulled downwards through a further distance of 20mm and released so that it oscillates about the static equilibrium position Neglecting air resistance, energy losses in the spring material and the mass of the spring determine () the periodic time and natural frequency of vibration, and (b) the maximum velocity and acceleration of the mass
