Question:

A mass on a spring is moving with simple harmonic motion. After a time t, the height h of the mass above its rest position is given by the following formula.

{eq}h = a\cos(\omega t - c) {/eq}

Find the height of the mass when a = 5.4 m, {eq}\omega = 3 \pi/17 {/eq}rad/s, t = 3 s, and{eq}c = 2 \pi/17 {/eq} rad.

Mass on a Spring

In solid state physics, the harmonic motion of a mass on a spring is also used to simulate the vibrations of atoms and molecules in a solid crystal. The vibration of atoms or molecules in a crystal is often called as phonon.

We can calculate for the height by simply substituting given values into the height formula.

{eq}h(t) = a\cos(\omega t - c)\\[0.2cm] h(3)=5.4\,\rm...
