Problem

A body of mass

0.50\,\text{kg}

executes simple harmonic motion with amplitude

6\,\text{cm}

and angular frequency

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

. If the amplitude is increased to

8\,\text{cm}

while all other parameters remain unchanged, determine the percentage change in its total mechanical energy.
