Problem

A particle of mass

0.50\,\text{kg}

executes SHM with amplitude

0.20\,\text{m}

and angular frequency

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

. Its displacement is given by

x(t)=A\cos(\omega t+\phi)

with phase constant

\phi=\tfrac{\pi}{3}

. Calculate the kinetic energy of the particle at

t=0.10\,\text{s}
