[SOLVED] Question about Applying V^2/r with two different velocities

1. The problem statement, all variables and given/known data
I have a problem where I am using the equation V^2/r = -1g to a problem with centripetal force. Basically the question is designing my own situation where i need to have a -1g acceleration on a turn and i decided on the picture below. It is a vertical picture.

2. Relevant equations
-1g = v^2/r

3. The attempt at a solution

I tried figuring out exactly how to get the velocity but I just don't seem to see which velocity to use.
