Problem

A vertical light spring of constant 500 N m−1500\,\text{N\,m}^{-1} is compressed by 0.10 m0.10\,\text{m} by a 1.0 kg1.0\,\text{kg} block resting on it. The block is then released from rest and leaves the spring when the spring reaches its natural length. Calculate the maximum height hh (measured above the spring’s natural length position) that the block will rise. Take g=9.8 m s−2g = 9.8\,\text{m\,s}^{-2}. (a) 0.52 m0.52\,\text{m} (b) 0.155 m0.155\,\text{m} (c) 0.26 m0.26\,\text{m} (d) 0.13 m0.13\,\text{m}
