The Kinetic Energy is the energy of a body or a system with respect to the motion of the bodyor of the particles in the system.
the usual expression for
K.E. = (1/2) mass . velocity^2
where m is the mass and v the velocity of the body
K.E. = (1/2) m . v^2
suppose the kinetic energy has increased to 4 times the original value.
but m= constant so v must have increased. so v must have becomes 2.v as K.E. is proportional to square of v .
therefore the momentum of the body must have changed to two times the original momentum.
