Actually, could be anything between 2 and 4 by varying how much mass and velocity you adjust. Usually it's just velocity, so the short answer is 4.

It depends on how you doubled the momentum. If you doubled the speed but kept the mass the same, then kinetic energy increased 4 times. If you doubled the mass but kept the speed the same, kinetic energy doubled. That is because momentum is MV and kinetic energy is 1/2MV^2.

it will increase by 1/2
bcoz momen. = mass*velocity
and kinetic e = 1/2*mass*(vel.^2)

an order of magnitude... the kenetic energy is squared.
Later Edit... see answers below... I blew it!
