Finding Lift Force - Glider Wing

[aaronmorg]

I am working on my semester project and have come across a hitch. I am trying to find the Lift Force of my wing using the following equation

F_L=C_L P A (v²/2)

Where:
F_L is Lift Force
C_L is Coefficient of Lift (I think)
P is the density of the fluid (Air)
A is the Area
V is Velocity

The only portion I cannot find is Velocity. I cannot, for the life of me, figured out Velocity when given force and mass.

I have a 3.33 lbf and a 27.999g aircraft.

Can someone please help me.

Equation so far:
F_L=(.76764)(.076)(56.55)(V²/2)

I found the equation for Horizontal Velocity. Here it is for anyone else who might be stuck in the same place.

V_H=\sqrt{\frac{2E}{m}}

E is energy
m is mass

In my case Energy was elasticity since my glider was flung from a rubber band. So I had to find ft-lbf, then use different conversion factors to get to a suitable velocity unit.

My work:

V_H=\sqrt{\left[\frac{2(4.1625)ft-lbf}{27.999g}\right]\left[\frac{453.6g}{1 lbm}\right]\left[32.2\frac{lbm-ft}{lbf-s}\right]}

Leaving me with Velocity in Ft/s

V_H= 65.899 ft/s

Additional Information:

I was given a chart, from whence I figured that 15 in displacement gave 3.33 lbf, and converted to ft-lbf, giving me my E.
