A 0.250 kg block on a vertical spring with a spring constant of 5.00 103 N/m is pushed downward, compressing the spring 0.120 m. When released, the block leaves the spring and travels upward vertically. How high does it rise above the point of release?
m

Equate the stored spring potential energy to the potential energy change at the highest elevation.
(1/2)k*X^2 = M g H
Solve for H 
h = 10.20408163 m
h = 10 m
