A spring is hung from the ceiling. A 0.560 kilogram block is then attached to the free end of the spring. When released from rest, the block drops 0.138 meter before momentarily coming to rest, after which it moves back upward.
(a) Obtain the spring constant of the spring?
(b) Obtain the angular frequency of the block vibrations.
