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
FL=CL P A (v2/2)
FL is Lift Force
CL 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:

I found the equation for Horizontal Velocity. Here it is for anyone else who might be stuck in the same place.
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.
Leaving me with Velocity in Ft/s
VH= 65.899 ft/s
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.
