Question

A block of mass m is attached to the end of an ideal spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance from its equilibrium length. The spring has an unknown spring constant k.

1) Suppose that the block gets bumped and undergoes a small vertical displacement. Find the resulting angular frequency w of the block's oscillation about its equilibrium position.
Express the frequency in terms of given quantities and g, the magnitude of the acceleration due to gravity.
2) What is the spring constant k? answer is k=mg/h

Answer 1

1) w=sqrt(k/m)

2) kh=mg
k=mg/h
