A particle of mass $0.3\,\text{kg}$ is fastened to one end of a light elastic string with natural length $0.8\,\text{m}$ and modulus of elasticity $6\,\text{N}$. The other end of the string is fixed at point $O$. The particle is projected vertically downwards from $O$ with initial speed $2\,\text{m s}^{-1}$.
