How Does Initial Velocity Direction Affect Spring Motion Velocities?

[hughes]

-The spring is stretched down and released with an initial velocity (v0) in the upward direction. The maximum velocity it reaches is v1.
-The spring is stretched down and released with an initial velocity (v0) in the downward direction. The maximum velocity it reaches is v2.

Rank the velocities. I said it was v1>v2>v1. The maximum velocity is reached at the middle of the path, and it is in the upward direction. I know I'm wrong; I just don't know how.

What are the initial KE and PE of the spring? At what height is the KE maximum? Can be the velocity both upward and downward at that point?
