The particle executing simple harmonic motion has a kinetic energy $K_0 \cos ^2$ $\omega t$. The maximum values of the potential energy and the total energy are respectively.
$K_0 / 2$ and $K_0$
$K_0$ and $2 K_0$
$K_0$ and $K_0$
0 and $2 K_0$.
Solution
$\because \mathrm{K}$. E. $=K_0 \cos ^2 \omega t$
$\therefore$ Maximum P. E. = Maximum K. E. $=$ Total energy $=\mathrm{K}_0$
