In the absence of friction, gravity, and all other external forces, what kind of speed will an object display if it travels from the bottom to the top of an inclined plane?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
