Physics Impulse as VALUE

Could someone please help me figure this out?

I have a ball that moves towards the mouse on click using a physics impulse. I use sin and cos to calculate the angle towards the mouse. Then I apply Physics Impulse to move at the speed of:

Impulse X (Calc_Gforce*Sprite.xvector)

Impulse Y (Calc_Gforce*Sprite.yvector)

<font color="blue">{Calc_Gforce is a preset Global Var, and xvector/yvector is an object var that is updated every tick with trajectory}</font>

How would I get the value of force for that impulse as a singular number every tick as I move the mouse around the screen before clicking? I want to create a FORCE BAR that will display how much force you will generate when clicking.

EDIT: - Updated file

To simplify, (a stink at math) I have X speed and Y Speed, but I need the Force (magnitude) of these two. I.E. The speed at which the ball will travel when the variable force is applied at X & Y simultaneously.
