Problem

A 0.5 kg0.5\,\text{kg} mass is attached to a horizontal spring of force constant 100 N m−1100\,\text{N m}^{-1}. The spring is compressed by 0.10 m0.10\,\text{m} and released from rest on a smooth horizontal surface. Calculate the speed of the mass as it passes through the natural (unstretched) length of the spring. (a) 2.0 m s−12.0\,\text{m s}^{-1} (b) 0.71 m s−10.71\,\text{m s}^{-1} (c) 1.4 m s−11.4\,\text{m s}^{-1} (d) 1.0 m s−11.0\,\text{m s}^{-1}
