Derivation of instantaneous velocity formula for middle position of a section of displacement Midpoint of displacement: v = root sign [(square of V0 + square of VT) / 2] How did you get out?

Derivation of instantaneous velocity formula for middle position of a section of displacement Midpoint of displacement: v = root sign [(square of V0 + square of VT) / 2] How did you get out?

The first formula: the entire 2As formula
The second formula: V ^ 2 - V0 ^ 2 = 2A * s / 2
Division of two forms
