Problem

A 2 kg2\,\text{kg} block starts from rest at the top of a smooth incline of height 1.0 m1.0\,\text{m} and slides down to strike a horizontal spring of constant 800 N m−1800\,\text{N\,m}^{-1}. Neglecting friction, the maximum compression produced in the spring is closest to (a) 0.31 m0.31\,\text{m} (b) 0.45 m0.45\,\text{m} (c) 0.22 m0.22\,\text{m} (d) 0.16 m0.16\,\text{m}
