Example #2 A 0.5 kg block is used to compresses a spring with a spring constant of 80.0 N/m a distance of 2.0 cm (.02 m ). The block is not attached to the spring and moves away with a final speed v f when the spring reaches its equilibrium length. What is v f ? 018m / s p pg q g A. 0.18 m/s B. 0.25 m/s C. 0.72 m/s
