Sorry also I forgot to mention that it makes sense in the fact that it will have enough velocity to reach a point y and its velocity will be zero and as it returns its velocity will return back to the original but negative. I was more so wondering how I could prove this with kinematics.

Hello, I'm new here and wasn't sure if this should be put into the homework section. It's not a homework question but the nature of the problem is homework-ish in nature I suppose. Anyway I'm trying to understand why a velocity vector along a parabola would have the same initial velocity as...
