I created two variables l and v and want to create l2 variable from LengthContractionRelativistic formula
l=Quantity[1,"Meters"]
v=Quantity[0.5, "SpeedOfLight"]
l2=FormulaData["LengthContractionRelativistic", {"v" ->Subscript["l",0]}]
It create l2 like next l==0.866025m but I want create l2 like 0.866025m to use it in expression l3=l2+Quantity[2,"Meters"] and so on.
How to assign l2 = 0.866025m by using LengthContractionRelativistic formula?
