I recommend using the work energy theorem. For a constant force it will be
[tex]F \Delta y = \Delta K.E. + \Delta G.P.E[/tex]
where G.P.E. is gravitational potential energy and is equal to [tex]mgy[/tex] . And K.E. is kinetic energy and is equal to [tex]1/2 mv^2[/tex]
(And please try next time to explain the problem a bit more clearly)
