Problem

A 0.60 kg0.60\,\text{kg} puck rests on top of a vertical spring of force constant 150 N/m150\,\text{N/m} that is compressed 0.25 m0.25\,\text{m} from its natural length. The puck is released from rest, rides upward on the expanding spring, loses contact exactly when the spring reaches its natural length, and then continues moving upward. Ignoring air resistance, how far above the point where it left the spring does the puck rise before momentarily coming to rest? (a) 0.33 m0.33\,\text{m} (b) 0.67 m0.67\,\text{m} (c) 0.55 m0.55\,\text{m} (d) 0.83 m0.83\,\text{m}
