A block of mass $m$ is placed on a frictionless surface and attached to a spring with spring cons ant $k$. The block is displaced from its equilibrium position by a dis ance $x_0$ and released from rest. Assuming the motion is simple harmonic, find the kinetic energy $K$ of the block at time $t$.

Question

A block of mass $m$ is placed on a frictionless surface and attached to a spring with spring cons	ant $k$. The block is displaced from its equilibrium position by a dis	ance $x_0$ and released from rest. Assuming the motion is simple harmonic, find the kinetic energy $K$ of the block at time $t$.

Accepted Answer

K = $ 1/2 $ m ω^2 x_0^2 \sin^2(ω t)
