Measured the vector relative velocity (magnitude and angle) of the Object 1 relative to Object 2. The angles are measured from the positive X axis, and the positive sense is the opposite of the clockwise.
|Object 1:||Object that relative velocity you want.|
|Object 2:||Object reference to measured the relative velocity.|
|v:||Magnitude of the vector relative velocity.|
|ang:||Angle of the vector relative velocity.|
