A verticаl spring (spring cоnstаnt =115 N/m) is mоunted оn the floor. A 0.590-kg block is plаced on top of the spring and pushed down to start it oscillating in simple harmonic motion. The block is not attached to the spring. Determine the amplitude at which the block will lose contact with the spring.
