Problem

0.20\,\text{kg}

mass performs simple harmonic motion with amplitude

0.10\,\text{m}

and angular frequency

5\,\text{rad\,s}^{-1}

. a. (i) Calculate its potential energy when the displacement from the mean position is

0.06\,\text{m}

. b. (ii) Express this potential energy as a percentage of the total mechanical energy of the motion.
