Calculating the amount of force needed to reach a distance

Unity Engine
1

Hello, I have been working on a leaping attack for the player and I have ran into a problem as far as forward distance. I am using this to calculate the force:

            force = 2*(distance / (jumpTime*jumpTime) - initialVelocity/jumpTime);
            rb.AddRelativeForce(Vector3.forward * force, ForceMode.Acceleration);

The problem I am facing is that the force turns out both negative, and isn’t enough to even budge the object. I got this by using the acceleration formula:
distance = intialVelocitytime + 0.5accelerationtime^2
distance - intialVelocitytime = 0.5accelerationtime^2
(distance - intialVelocitytime)/(0.5time^2) = acceleration
2*(distance/time^2 - intialVelocity/time) = acceleration

And I am capturing the intialVelocity in an instant from GetComponent().velocity.magnitude. I haven’t a clue as to why this is happening.
