Here we can talk about conservation of energy. mass m will have potential energy of mgh and mass 2m will have potential energy of 4mgh. after dropping the masses, both will acquire kinetic energy and when the masses is just to reach the ground their potential energy will completely convert into kinetic energy, Potential energy of mass 2m is greater so kinetic energy will also be greater.

Answer:
Body with mass 2m will have a greater kinetic energy, because it has greater height and mass, and hence greater potential energy
