For each of the situations below, write three differentequations for x(t) that all describe the samemotion. One of your three equations must use sine, one of yourthree equations must use cosine, and at least one must use anon-zero phase shift (Ï•), whose value you should specify.
- A mass-spring system of angular frequency ω is stretched tox=+A and released. The time is started so thatt=0 is when the mass passes through the equilibriumposition at x=0 the first time.
- A mass-spring system of angular frequency ω is compressed tox=-A and released. The time is started so thatt=0 is when the mass is released from its compressedposition.
