If force is the lifting force, then it will be a function of both velocity (speed) and angle,
L = f(s,theta)
velocity (speed) will be a function of acceleration and time,
S = a*t
Weight will be a function of mass, W = m*g (g is acceleration due to gravity)
substitute...
L = f(a*t,theta)
When L >= W, you have liftoff
set the equations for L and W equal to each other and solve for s to find the takeoff velocity for a given angle (and it will be different for different angles).

Have you drawn a picture of the problem yet? Do you understand what the problem is actually asking you to do? What is the meaning of force, acceleration, and velocity and how do they relate?
You have to be able to visualize, understand, and conceptualize a problem to get a solution. An equation alone is not the way to do it.
