A 0.340 kg block on a vertical spring with a spring constant of 4.09 × 103 N/m is pushed downward, compressing the spring 0.0700 m. When released, the block leaves the spring and travels upward vertically.

Question

A 0.340 kg block on a vertical spring with a spring constant of 4.09 × 103 N/m is pushed downward, compressing the spring 0.0700 m. When released, the block leaves the spring and travels upward vertically.
The acceleration of gravity is 9.81 m/s2 .
How high does it rise above the point of release?
Answer in units of m
