Problem

0.50\,\text{kg}

block attached to a spring oscillates with amplitude

0.20\,\text{m}

on a frictionless horizontal surface. The spring constant is

25\,\text{N/m}

. What is the kinetic energy of the block when its displacement from equilibrium is

0.10\,\text{m}

? a)

0.125\text{ J}

0.500\text{ J}

0.375\text{ J}

0.250\text{ J}
