Which of the following statements about the oscillatory movement of a block attached to a spring is/are true? I) The amplitude of the block's oscillatory movement is 20cm. II) The block completes 5 cycles every second. III) The period of the oscillatory movement is 0.2s. IV) The block has zero velocity when passing through the equilibrium position. V) The velocity is maximum at the points of inversion.

I, III, and IV are true.
II and V are true.
Only III is true.
I, II, and V are true.
