4.14 Relative velocity

Measure the relative velocity of mobile Object 1 relative to mobile Object 2. The angle is measured from the positive X axis, the positive sense is the opposite of clockwise. Also, this element can be used to measure the relative velocity (in this case the total velocity) of a Mobile with polar circular motion relative to its center of rotation.

Equations:	2
Data:
Object 1:	Name of first mobile.
Object 2:	Name of second mobile.
v:	Magnitude of the relative velocity.
ang:	Angle of the relative velocity vector.
