A block of mass 0.14 kg is placed on a vertical spring of constant 5723 N/m and pushed downward, compressing the spring 0.08 m. After the block is released it leaves the spring and continues to travel upward. The acceleration of gravity is 9.8 m/s2. What height above the point of release will the block reach if air resistance is negligible?
