A spring with a Hooke's law constant of 45 N/m an an unstretched length of 18 cm is hung vertically from a support. A block is attached to the free end of the spring and let go from rest; the lowest point reached by the mass is 30 cm from the support attachment.

Determine (a) the amplitude of vibration; (b) the mass of the block, (c) the period and frequency of vibration; and (d) the maximum speed of the block while vibrating.
