A spring is hung from the ceiling. A 0.459 -kg block is then attached to the free end of the spring. When released from rest, the block drops 0.199 m before momentarily coming to rest, after which it moves back upward.
(a) What is the spring constant of the spring?
(b) Find the angular frequency of the block's vibrations.
