A particle of mass $0.3\text{ kg}$ is subjected to a force $F=-kx$ with $k=15\text{ N/m}$. What will be its initial acceleration if it is released from a point $20\text{ cm}$ away from the origin?

1. A
   $3{\text{ m/s}}^2$
2. B
   $15{\text{ m/s}}^2$
3. C
   $5{\text{ m/s}}^2$
4. D
   $10{\text{ m/s}}^2$
