How do I Get total/resultant velocity?

The Physics behavior has these expressions: "VelocityX" and "VelocityY", and it has a condition for "Compare (total) velocity". However, I can't see a way to get the value for "total velocity" itself .

I've looked up the formula online but can't wrap my head around it. They seem to be teaching how to get Vx and Vy, given the total/resultant velocity and angle while in C2, it's the other way around, i.e. the Vx and Vy are known and the total/resultant velocity (while seemingly known since there's a condition for it) is not accessible to the user.

I need to know how to get total/resultant velocity given Vx and Vy. Thanks in advance!

High school math class: the hypotenuse is equal to the square root of the sum of the squares of the two opposite sides. Speed being a direct derivative of distance, we can surmise that the same is true for speed also. Therefore:

Speed = sqrt( ( VelocityX^2 ) + ( VelocityY^2 ) )

[ Edit: in honesty I had to Google this, but did so by Googling 'converting two vectors to velocity' - which is as embarrassing for me as it should be for you ]

Yeah I am glad you added that edit as I knew there was a formula I learned in engineering but no way I could pull that out and drop it without looking it up first lol!

You can also use the distance expression, after all it's the same equation.

distance(0,0,velocityX,velocityY)

Thanks! Yes, it's embarrasing The distance thing is very helpful as well!
