# Simple Harmonic Motion Mass Hanging Spring.

A certain spring with its upper end attached to a ceiling and nothing attached to its lower end has a length s= .6 m. When a mass M= 2.0 kg is attached to hang from its lower end the spring then has a length h= .80 m.

See ATTACHMENT for a diagram showing parameters.

The mass is raised .15 m above equilibrium point and released from rest to begin SHM.

For a vertical x axis with origin at the equilibrium level and positive locations above this point, develop the location function x(t).

#### Solution Preview

Step 1.

The general expression giving x(t) for a body moving with SHM is:

(1) x = Xm cos (w t + Q) in which w is the angular frequency in rad/sec, Q is the initial phase angle, and ...

#### Solution Summary

The expert examines SHM mass hanging springs. A vertical axis with origins at the equilibrium level and positive locations are found.
