A block of mass $m$ is attached to a horizontal, massless spring with a spring cons ant $k$. The block is displaced by a dis ance $x$ from its equilibrium position and released from rest. Assuming the block undergoes simple harmonic motion, what is the kinetic energy of the block at time $t$?

A block of mass $m$ is attached to a horizontal, massless spring with a spring cons	ant $k$. The block is displaced by a dis	ance $x$ from its equilibrium position and released from rest. Assuming the block undergoes simple harmonic motion, what is the kinetic energy of the block at time $t$?

Accepted Answer

$K = \frac{1}{2}momega^2x^2\sin^2(omega t)$
