In this problem, we're going to use the law of conservation of energy.
It states that the initial potential energy is equal to the energy stored in the spring.
, where m is mass, x is spring compression, and k is spring constant.
A spring is hung from the ceiling. A 0.400-kg block is then attached to the free end ofthe spring. When released from rest, the block drops 0.130 m before momentarily coming to rest, afterwhich it moves back upward.
(a) What is the spring constant of the spring?
(b) Find the angular frequency of the block's vibrations.
