Is there friction? Is it accelerating from an initial speed of zero? More information is needed.

If it starts out with zero velocity, it acquires a final speed of 6 m/s. (Twice the average speed).

If there is no friction, final KE = Work done.

(1/2)M*Vfinal^2 = Force*Distance

Solve for the force
