A spring is hung from the ceiling. A 0.596 -kg block is then attached to the free end of the spring. When released from rest, the block drops 0.120 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.
